Guide

Content-browser assets: find/query the registry, lifecycle (create, duplicate, rename, move, delete, save, single + bulk), dependencies and redirectors, validation, metadata, folders, thumbnails, source control, content browser control, factories for the common simple asset types, collections, package and disk facts, bulk organisation, structured content (data tables, curves, string tables, data assets) and advanced file import/export. The kit spans seven classes (UUeaKit_Asset, UUeaKit_AssetCollections, UUeaKit_AssetRegistry, UUeaKit_AssetPackages, UUeaKit_AssetSourceControl, UUeaKit_AssetData, UUeaKit_AssetImport), all registering as kit asset, over two prefixes.

Prefix	Tools	What it covers
asset.	191	registry queries and graphs, lifecycle (single + bulk), collections, packages/disk/dirty state, path and name helpers, bulk organisation, source control, validation, metadata, folders, thumbnails, content browser, factories, data tables, curves, string tables, data assets
import.	24	typed importers (texture, static/skeletal mesh, animation, sound, glTF), configured and batched imports, factory option discovery, reimport management, exporters

215 tools in total (214 on UE 4.27: import.interchange_info needs 5.1+). Every tool takes JSON arguments named after the C++ struct fields in camelCase without the b prefix (bRecursive -> recursive). Asset references accept an object path (/Game/Folder/Asset.Asset), a package path (/Game/Folder/Asset) or a unique bare name.

Start here

1. asset.find {name, folder, class, recursive, limit} and asset.get_summary {asset} are core tools: always listed, regardless of exposure mode or kit activation.
2. edit.search_tools {query:"import mesh"} finds tools by words in name + description; edit.get_tool_schema {tool:"asset.rename_many"} gives the full input/output JSON schema.
3. edit.enable_kits {kits:["asset"]} advertises every asset.* / import.* tool in Adaptive mode (they stay callable either way).

Tools

asset. (registry, lifecycle, dependencies, factories)

Tool	Purpose
asset.find {name, folder, class, recursive, limit} / asset.list_folder {folder} / asset.exists / asset.exists_many {assets}	Search by name substring + folder + class; folder listing; existence checks (registry only, nothing loaded).
asset.get_summary / asset.get_registry_tags / asset.get_file_info / asset.get_state_many	Class, parent, dirty state, dependencies, referencers, first 60 properties; registry tags (ParentClass, RowStructure...); file size/timestamp/cooked; bulk loaded/dirty/size.
asset.list_classes {folder} / asset.count {folder, class} / asset.find_by_class {class, includeDerived, onDiskOnly} / asset.find_by_tag {tag, value, contains} / asset.find_blueprints_by_parent {parentClass, includeSubclasses}	Registry queries.
asset.get_size_report {folder, class, limit} / asset.list_recent / asset.find_unused {class, folder}	Largest assets + totals per class; most recently modified files; assets nothing references.
asset.get_dependencies / asset.get_referencers (hard, soft, recursive, maxDepth, includeScript) / asset.find_circular_dependencies	Dependency graph walks (each entry carries depth and via); A -> B -> A cycles.
asset.list_redirectors {folder} / asset.fix_redirectors {folder, recursive, dryRun, save}	Redirectors left by renames/moves; fix_redirectors loads the referencing packages, repoints them at the real assets and deletes the redirectors. It never prompts (the engine's own FixupReferencers ends in a modal report window and is not used). Run with dryRun:true to list the redirectors and their referencers first; pass save:true to write the updated referencers to disk.
asset.validate {assets}	Data validation (IsDataValid + registered validators).
asset.create_folder {folder} / asset.duplicate {asset, folder, newName} / asset.rename / asset.move {asset, folder}	Single-asset lifecycle (rename/move fix up referencers).
asset.duplicate_many {assets, folder} / asset.move_many / asset.rename_many {folder, find, replace, prefix, suffix, class, dryRun} / asset.delete_many {assets, force}	Bulk versions; per-asset failures are reported instead of stopping. rename_many with dryRun:true previews.
asset.delete / asset.consolidate {target, assets}	Delete one asset (refuses while referenced); merge duplicates into target and delete them.
asset.save / asset.save_many {assets} / asset.save_all	Write packages to disk. Nothing is auto-saved.
asset.create_folders {folders} / asset.rename_folder {folder, newFolder} / asset.duplicate_folder / asset.delete_folder / asset.folder_has_assets	Content folders.
asset.get_metadata / asset.set_metadata {asset, key, value} / asset.remove_metadata	Editor metadata tags (UMetaData).
asset.set_texture_settings {asset, srgb, compression, lodGroup, mipGen, maxSize, neverStream, save}	Post-import texture settings (-1 / empty / 0 keep).
asset.render_thumbnail {asset, size, savePath}	Thumbnail as a PNG image block (32-1024 px).
asset.get_source_control_state {assets} / asset.checkout / asset.revert	Source control on assets.
asset.open_editor / asset.get_open_editors / asset.close_editor / asset.close_all_editors	Asset editor windows.
asset.sync_browser {assets} / asset.set_browser_folder {folder} / asset.get_browser_folder / asset.get_browser_selection	Content Browser navigation and selection.
asset.create {class, folder, name, factory, factoryProperties, save} / asset.list_factories {contains}	Any class with a "new asset" factory; the factory list with supported class and import extensions.
asset.create_material / create_material_instance {source:parent} / create_material_function / create_data_table {source:rowStruct} / create_curve {type:float|vector|linearcolor} / create_enum {values} / create_struct {fields:[{name, type, default}]} / create_data_asset {source:class} / create_level {source:template} / create_render_target {width, height} / create_font / create_sound_cue {source:wave} / create_sound_class / create_sound_mix / create_physical_material {source:subclass} / create_physics_asset {source:skeletalMesh} / create_string_table / create_object_library	Typed factories; all take folder, name, save. Struct field types use the bp type syntax (float, object:Actor, struct:HitResult, append [] for arrays).
asset.data_table_fill {asset, text|file, format} / asset.data_table_export {asset, format, savePath}	DataTable rows from/to CSV or JSON (fill replaces existing rows).
asset.string_table_list / asset.string_table_set {asset, entries:[{key, value}]}	StringTable entries.
asset.import_file {file, folder, name}	Automatic importer, no dialogs (FBX, PNG, WAV, ...); simple single-asset variant of import.files.

import. (files in and out)

Tool	Purpose
import.files {files, folder}	Automatic importer, no dialogs, many files at once.
import.texture {file, folder, srgb, compression, lodGroup, mipGen}	Texture with settings applied at import.

asset. (collections)

Tool	Purpose
asset.list_collections {contains, shareType, includeCounts} / asset.get_asset_collections {asset, recursive}	Collections with share type, storage mode, parent, colour and asset count; which collections hold an asset.
asset.create_collection {name, shareType, storageMode, parent, query} / asset.delete_collection {collection, recursive} / asset.rename_collection {collection, newName, newShareType} / asset.reparent_collection {collection, parent}	Lifecycle and nesting. Names are sanitised (letters, digits, _, -); shareType is local (default), private or shared; storageMode is static or dynamic (a saved content-browser query).
asset.add_to_collection {collection, assets} / asset.remove_from_collection / asset.get_collection_assets {collection, recursive, limit} / asset.empty_collection	Static collection contents.
asset.collection_from_search {name, folder, classFilter, nameContains, limit}	Creates (or refills) a collection from a registry search in one call.
asset.set_collection_color {collection, r, g, b, a, clear}	Content browser colour.

Tool	Purpose
asset.query {packagePaths, classes, recursiveClasses, recursivePaths, tags:[{key,value}], packageNames, onDiskOnly, includeTags, limit, offset}	The full FARFilter in one call, with paging. Start here for anything the narrow finders cannot express.
asset.get_by_package {package, includeTags} / asset.list_by_tag_value {tag, value, folder} / asset.list_tags_of_class {class, folder, sampleSize}	Objects inside one package; exact tag/value matches; the distinct tag keys a class carries, with an example value each.
asset.get_derived_classes {class, recursive, limit} / asset.get_class_ancestors {class}	Class hierarchy from the registry (native classes and Blueprint generated classes).
asset.list_paths {base, recursive} / asset.path_exists {path} / asset.scan_paths {paths, force} / asset.scan_files {paths, force}	Content folders known to the registry; force a synchronous rescan after writing files outside the editor.
asset.registry_status / asset.wait_for_registry {timeoutSeconds}	Whether the initial scan finished; wait_for_registry lets editor frames pass until it does.
asset.get_dependency_graph {asset, depth, hard, soft, searchable, manage, includeScript, limit} / asset.get_referencer_graph	Edge lists (from, to, category, hard, depth) up to depth 4, downward and upward.
asset.find_orphans {folder} / asset.find_missing_references {folder} / asset.find_duplicates_by_name {folder} / asset.diff_folders {a, b}	Audits: nothing outside the folder references them; references to packages that no longer exist; same name in several folders; folder comparison by asset name.
asset.get_asset_size_breakdown {folder, groupBy:"class" or "subfolder"} / asset.list_largest {folder, class, limit}	Disk size grouped or ranked.

asset. (packages, paths and bulk organisation)

Tool	Purpose
asset.get_package_info {asset} / asset.list_loaded_packages {folder, dirtyOnly} / asset.fully_load {asset}	File on disk, size, load/dirty state, PKG flags, objects in the package.
asset.list_dirty / asset.mark_dirty {assets} / asset.clear_dirty {assets} / asset.save_dirty {prompt, includeMaps, includeContent}	Unsaved-change handling. clear_dirty drops the flag without saving.
asset.unload_packages {packages, includeDirty} / asset.reload_packages	Free memory / discard in-memory changes.
asset.sanitize_name {name} / asset.make_unique_name {folder, base, suffix} / asset.validate_path {path} / asset.split_path {path}	Name and path helpers; split_path returns package, asset, sub-object, mount point, folder and the file on disk.
asset.list_mount_points / asset.list_content_plugins	Content roots (/Game/, /Engine/, plugin mounts) and enabled plugins with content.
asset.organize_by_class {folder, mapping:[{class, subfolder}], dryRun} / asset.apply_naming_prefix {folder, mapping:[{class, prefix}], dryRun} / asset.find_naming_violations {folder, mapping}	Bulk organisation. Defaults: Blueprints/Materials/Textures/Meshes/Sounds and BP_, M_, MI_, MF_, T_, SM_, SK_, S_.
asset.move_folder {folder, newParent} / asset.list_empty_folders {folder} / asset.delete_empty_folders {folder, dryRun} / asset.copy_folder_to_plugin {folder, plugin, subfolder}	Folder moves and cleanup; the plugin copy is an advanced copy (dependencies follow).

asset. (source control per asset)

Tool	Purpose
asset.sc_get_provider / asset.sc_status {assets, updateStatus}	Provider name/enabled/available; per-asset checked out (and by whom), modified, added, deleted, current, conflicted, revision.
asset.sc_checkout_many {assets} / asset.sc_add_many / asset.sc_revert_many {assets, unchangedOnly} / asset.sc_checkin {assets, description, keepCheckedOut}	The everyday operations.
asset.sc_sync {assets or folder} / asset.sc_history {asset, limit} / asset.sc_diff_against_depot {asset} / asset.sc_list_changed {folder}	Sync to head; revision list; fetch the head revision and report whether the local file differs; locally changed files under a folder.
asset.sc_lock {assets} / asset.sc_unlock	Locking, where the provider supports it. The engine provider interface has no separate lock operation, so lock is a check out and unlock a revert of an unmodified check out (the reply's hint says so).

Every source control tool answers E_NOT_SUPPORTED with a clear message when no provider is enabled.

asset. (data tables, curves, string tables, data assets)

Tool	Purpose
asset.data_table_info {asset} / asset.data_table_set_row_struct {asset, rowStruct}	Row struct, typed columns, row count, composite parents. Changing the row struct drops every row.
asset.data_table_list_rows {asset, nameContains, includeValues, limit, offset} / asset.data_table_get_row {asset, row} / asset.data_table_find_rows {asset, column, value, contains}	Reading rows. Columns are addressed by their authored name (what the editor shows).
asset.data_table_add_row {asset, row, values:[{key,value}]} / asset.data_table_set_cell {asset, row, column, value} / asset.data_table_set_row / asset.data_table_duplicate_row {row, newName} / asset.data_table_rename_row / asset.data_table_reorder_row {row, direction, steps} / asset.data_table_remove_row / asset.data_table_clear	Row CRUD. Values are the same text the details panel accepts; unknown columns come back in problems instead of failing the call.
asset.data_table_import_csv {asset, csv or file} / asset.data_table_import_json {asset, json or file} / asset.data_table_export_json {asset}	Whole-table import (replaces the rows) and JSON export. asset.data_table_export (CSV or JSON) still exists on the original class.
asset.composite_table_set_parents {asset, parents}	Parent tables of a CompositeDataTable, lowest priority first.
asset.curve_info {asset, channel} / asset.curve_get_keys / asset.curve_evaluate {asset, time, channel}	Curve channels: value (CurveFloat), x/y/z (CurveVector), r/g/b/a (CurveLinearColor). Empty channel means every channel.
asset.curve_add_key {asset, time, value, interp} / asset.curve_set_keys {asset, channel, keys} / asset.curve_remove_key {asset, index or time} / asset.curve_clear / asset.curve_set_interpolation {asset, interp}	Key editing. interp is linear, constant, cubic or none.

asset.data_asset_get {asset} / asset.data_asset_set {asset, values:[{key,value}], save} / asset.list_data_assets {class, folder}	Editable properties of any DataAsset as text.
asset.list_primary_assets {type, limit} / asset.get_primary_asset_id {asset} / asset.asset_manager_scan {paths, type, baseClass, hasBlueprintClasses, editorOnly}	Asset manager: registered types, the id of an asset, and registering a folder as a primary asset type.

import. (advanced import and export)

Tool	Purpose
import.get_options {format, includeOptionsObject} / import.list_importable_extensions / import.list_exporters {class}	Discovery. get_options returns the factory's editable properties with their defaults and the keys to pass to import.with_options (including nested ones such as ImportUI.bImportMaterials).
import.with_options {file, folder, name, factory, options:[{key,value}], replaceExisting, save} / import.batch {tasks, save}	Configured imports through UAssetImportTask; batch runs every task in one ImportAssetTasks call and reports per task.
import.fbx_static_mesh / import.fbx_skeletal_mesh / import.fbx_animation	Typed FBX imports with named arguments instead of factory property paths (lightmap UVs, collision, combine, morph targets, physics asset, skeleton, frame range, scale, axis conversion).
import.texture_with_settings {file, folder, compression, srgb, mipGen, lodGroup, maxSize, flipGreen} / import.audio {file, folder, compressionQuality, looping, soundGroup}	Typed texture and sound imports, settings applied right after the import.
import.csv_to_data_table {file, rowStruct, folder, name} / import.json_to_data_table	Create a DataTable from a file on disk in one call.
import.gltf {file, folder, name, options}	glTF/GLB through whichever glTF importer the engine has.
import.can_reimport {asset} / import.get_source_files {asset} / import.set_source_file {asset, file, index} / import.reimport_many {assets, askForNewFiles} / import.reimport_folder {folder, classFilter, dryRun}	Reimport management; get_source_files also reports which recorded files are gone.
import.export_many {assets, directory, extension} / import.export_to_fbx {asset, file, options} / import.export_texture {asset, file} / import.export_data_table_csv {asset, file}	Exporting.
import.get_last_import_log / import.interchange_info (5.1+)	Warnings and errors captured during the last import/export call of this kit; whether Interchange is present and enabled.

Recipe: import and wire a prop

edit.call_many {
  "calls": [
    {"tool": "asset.create_folder", "argsJson": "{\"folder\":\"/Game/Props\"}"},
    {"tool": "import.static_mesh", "argsJson": "{\"file\":\"D:/Art/Crate.fbx\",\"folder\":\"/Game/Props\",\"name\":\"SM_Crate\"}"},
    {"tool": "asset.create_material_instance", "argsJson": "{\"folder\":\"/Game/Props\",\"name\":\"MI_Crate\",\"source\":\"/Game/Materials/M_Base\"}"},
    {"tool": "asset.save_many", "argsJson": "{\"assets\":[\"/Game/Props/SM_Crate\",\"/Game/Props/MI_Crate\"]}"}
  ],
  "stopOnError": true
}

argsJson is a JSON object string; each result carries ok, resultJson and milliseconds. Wrap the batch in edit.begin_transaction {title:"Import crate"} ... edit.end_transaction when the user should be able to undo it in one step.

Recipe: asset dependency cleanup

1. asset.list_redirectors {folder:"/Game", recursive:true} -> asset.fix_redirectors {folder:"/Game"}.
2. asset.find_unused {class:"Object", folder:"/Game/Old"} (maps and assets referenced only by /Script/ count as unused) and asset.get_size_report {folder:"/Game"} to pick targets.
3. Before deleting: asset.get_referencers {asset:"T_Old", recursive:true, maxDepth:2} and asset.find_circular_dependencies {asset:"BP_Hub"}.
4. asset.consolidate {target:"/Game/Textures/T_Rock", assets:["/Game/Old/T_Rock2", "/Game/Old/T_Rock_copy"]} redirects every reference and deletes the duplicates; asset.delete_many {assets:[...]} for the rest (force:true nulls out remaining references, so avoid it unless the referencers are being deleted too).
5. asset.validate {assets:[...]} on the survivors, then asset.save_all.

Recipe: organise a messy folder

1. asset.find_naming_violations {folder:"/Game/Imported"} and asset.organize_by_class {folder:"/Game/Imported", dryRun:true} - read the planned changes.
2. Adjust with an explicit mapping when the defaults are wrong ([{"class":"Texture","subfolder":"Tex","prefix":"TX_"}]).
3. Run both for real: asset.apply_naming_prefix {folder, dryRun:false} first, then asset.organize_by_class {folder, dryRun:false} (rename before moving).
4. asset.fix_redirectors {folder:"/Game", recursive:true} to clean up after the moves.
5. asset.list_empty_folders {folder:"/Game/Imported"} -> asset.delete_empty_folders {folder:"/Game/Imported", dryRun:false}.
6. asset.save_dirty {prompt:false} (or asset.save_all).

Recipe: fill a data table

1. asset.create_data_table {folder, name, source:"MyRowStruct"} (or asset.data_table_set_row_struct on an existing one - it drops every row).
2. asset.data_table_info {asset} to read the column names to use (authored names).
3. asset.data_table_add_row {asset, row:"Sword", values:[{"key":"Damage","value":"12"}]} per row, or import.csv_to_data_table / asset.data_table_import_csv for a whole file.
4. asset.data_table_find_rows {asset, column:"Damage", value:"12"} to verify and asset.data_table_export_json {asset} to read it back.
5. asset.save {asset}.

Recipe: collections as a working set

1. asset.collection_from_search {name:"ReviewMe", folder:"/Game/Characters", classFilter:"SkeletalMesh"}.
2. asset.add_to_collection {collection:"ReviewMe", assets:[...]} for extras and asset.set_collection_color {collection:"ReviewMe", r:1, g:0.6, b:0.1} to make it visible.
3. asset.get_collection_assets {collection:"ReviewMe"} feeds any bulk tool.
4. asset.delete_collection {collection:"ReviewMe", recursive:true} when done (assets are untouched).

Recipe: import with exact factory options

1. import.get_options {format:"fbx"} - the options list gives every key and its default, including nested ones such as ImportUI.bImportMaterials.
2. import.with_options {file, folder, name, options:[{"key":"ImportUI.bImportMaterials","value":"false"}]}, or import.batch {tasks:[...]} for a whole directory in one call.
3. import.get_last_import_log for the warnings the importer produced.
4. import.can_reimport {asset} / import.set_source_file when the source moved, then import.reimport_many {assets} (or import.reimport_folder {folder, dryRun:true} first).

Gotchas

• Tools marked Mutates in the schema run inside an editor transaction and are undoable with edit.undo; edit.begin_transaction groups several into one step. File imports on disk are not transactional (the source file itself is untouched, but the created asset is).
• Destructive tools: asset.delete, asset.delete_many (force:true nulls references), asset.delete_folder, asset.consolidate, asset.revert. asset.delete refuses while referencers exist; check asset.get_referencers first.
• asset.delete, asset.delete_many and asset.delete_folder are NonUndoable (reply undoable:false): the packages are removed from disk, and when the undo history still references a deleted asset (for example through a deleted actor) the history is cleared, as the editor's own delete does. References held by deleted actors are cleared too, so the same path can be created again in the same session. edit.call_many {atomic:true} and atomic edit.run_workflow refuse them up front; delete in a separate call (workflow cleanup lists run their steps directly). A checkpoint rollback after a delete reports non_undoable_call (and history_reset when the history was cleared) and never claims complete.
• Nothing is auto-saved: asset.save / asset.save_many / asset.save_all (or save:true on the create/import tools) write to disk. asset.save_all before play.start so PIE sees the latest compiled state.
• asset.rename_many and asset.find_unused can touch hundreds of assets: use dryRun:true and a folder filter first. Bulk tools (*_many, asset.validate) report per-item failed entries instead of aborting.
• Source control tools (asset.checkout, asset.revert, asset.get_source_control_state) do nothing useful when edit.sc_info reports enabled:false.
• Two tools in this kit can open a modal window and must never be called from an unattended editor: asset.copy_folder_to_plugin (the engine's advanced copy prompts to save, then confirms) and asset.save_dirty with prompt:true. Everything else in the kit is dialog-free by construction; asset.consolidate writes the dirtied packages to disk as part of the operation.
• import.* and asset.import_file need a source file on disk reachable by the editor process; they are not smoke-tested for that reason (see Docs/dev/KIT_AUTHORING.md).
• Collections are project-global state stored next to the project, not content assets: they are not undoable with edit.undo and asset.delete_collection is permanent. Names are sanitised, so "My Set" becomes My_Set - use the sanitised name in follow-up calls (every reply echoes it).
• asset.organize_by_class, asset.apply_naming_prefix and asset.delete_empty_folders move or delete in bulk: run them once with dryRun:true and read changes / folders first, then run asset.fix_redirectors afterwards.
• asset.unload_packages, asset.reload_packages and asset.clear_dirty discard work. They refuse dirty packages unless includeDirty:true, and anything another tool reported about those packages is stale afterwards.
• Data table columns of a user-defined struct have mangled internal names; address them by their authored name (asset.data_table_info lists both). Unknown columns are reported in problems rather than failing the whole write.
• asset.get_derived_classes and asset.get_class_ancestors answer from the asset registry, which only knows what it scanned: call asset.scan_paths first when a Blueprint was just written to disk outside the editor, and asset.wait_for_registry right after startup.
• import.get_options is the reliable way to find an option key: factory property names differ per engine version, and import.with_options reports unknown keys as warnings in log instead of failing the import.

Tools

Legend. risk 0 = read-only, 1 = harmless editor op, 2 = modifies asset, 3 = deletes/replaces asset, 4 = project/config/build op, 5 = potentially destructive (calls above MaxAutoRisk need "_confirm": true). mutates = runs in a transaction (edit.undo reverts). requires PIE / requires world = refused without a PIE session / an open level. requires plugin = unavailable while the plugin is disabled. dryRun = honours the dryRun argument. smoke = covered by edit.self_test.

collection	string	required.
shareType	string	Default TEXT("local").
assets	array of string	required. Assets to add/remove (object path, package path or unique name).

Returns: collection, message, assets, count.

asset.apply_naming_prefix (risk 3, mutates, dryRun, smoke)

Renames assets so each class carries its naming prefix (BP_, M_, MI_, T_, SM_, SK_, S_ by default). Run with dryRun first.

limit	integer	Default 500.

Returns: changes, count, failedCount, dryRun, rulesUsed.

asset.asset_manager_scan (risk 1, smoke)

Registers content folders with the asset manager as a primary asset type and scans them.

Argument	Type	Description
paths	array of string	required. Content folders to scan, e.g. ["/Game/Items"].
type	string	required. Primary asset type to register the results under.
baseClass	string	required. Base class of the primary assets, e.g. "PrimaryDataAsset".
