Kit `mesh`

155 herramientas. Generado a partir del código fuente del plugin; no lo edites a mano.

Las descripciones de las herramientas y de los argumentos se muestran en inglés porque reflejan el schema de las herramientas (el mismo texto que el agente recibe en tools/list).

Guía

Static and skeletal mesh assets: LOD chains, build and reduction settings, materials and sections, sockets, simple and complex collision, UV channels and lightmap UVs, Nanite and distance fields, procedural authoring with Geometry Script, skeletal mesh basics (bones, morph targets, physics assets, skeleton binding) and folder-wide audits.

Works on UE 4.27 through 5.8 (123 tools on 4.27, 155 on 5.8). The extra 5.x tools are Nanite and the whole mesh.gs_* Geometry Script family; they are hidden from tools/list on older engines and refused with E_NOT_SUPPORTED if called anyway.

The kit is split over six classes that all expose the mesh. namespace:

Class	Prefix	What
`UUeaKit_Mesh`	`mesh.`	info, LODs, build settings, materials, sections, sockets, lightmap, distance field, Nanite, bounds, import settings, duplicate/rename/delete/export/merge/validate
`UUeaKit_MeshCollision`	`mesh.`	simple collision primitives, convex decomposition, complexity, physical material, per-section collision, collision audits
`UUeaKit_MeshUV`	`mesh.`	UV channels, projections, lightmap UVs, UV bounds, tiling, auto-UV
`UUeaKit_MeshGeometry`	`mesh.gs_`	Geometry Script primitives and operations (UE 5 + the GeometryScripting plugin)
`UUeaKit_SkeletalMesh`	`mesh.sk_`	skeletal mesh LODs, materials, sockets, bones, morph targets, physics assets, skeleton
`UUeaKit_MeshBatch`	`mesh.`	folder audits and bulk edits

Not here: placing meshes in a level (actor kit), mesh component settings (component kit), importing FBX (asset kit asset.import_*), materials themselves (material kit).

Start here

mesh.get_info {"mesh":"/Game/Meshes/SM_Rock"} — LODs with triangle/vertex/section counts, materials, sockets, bounds, lightmap, collision summary, Nanite, LOD group, source files.
mesh.audit {"folder":"/Game/Meshes"} — the whole folder with triangle budgets, LOD coverage, missing collision and lightmap resolution, plus the offenders.
mesh.validate {"mesh":"..."} — one mesh checked for a broken LOD chain, missing collision, unusable lightmap UVs and empty material slots.
mesh.report {"folder":"/Game/Meshes"} — the same audit as markdown text for a human.

Everything that changes an asset is transactional (edit.undo works) but nothing is saved until you call mesh.save or asset.save_all.

Recipes

A production-ready prop in three calls

mesh.generate_lods   {"mesh":"/Game/Meshes/SM_Crate","count":3}
mesh.auto_convex_collision {"mesh":"/Game/Meshes/SM_Crate","hullCount":4,"maxHullVerts":16}
mesh.generate_lightmap_uv  {"mesh":"/Game/Meshes/SM_Crate","srcChannel":0,"dstChannel":1,
                            "minResolution":64}

mesh.generate_lods rebuilds the whole LOD chain from LOD0 by reduction (default percentages 0.5, 0.25, 0.125…), mesh.auto_convex_collision replaces the simple collision with a convex decomposition, and mesh.generate_lightmap_uv turns on the engine's lightmap UV generator and points the lightmap coordinate index at the new channel.

Collision from scratch

mesh.fit_collision_to_bounds {"mesh":"...","kind":"box"}        // one box on the bounds
mesh.add_capsule_collision   {"mesh":"...","radius":30,"length":80}
mesh.set_collision_complexity{"mesh":"...","complexity":"use_simple_as_complex"}
mesh.get_collision           {"mesh":"..."}                     // check the result

Shapes: box, sphere, capsule, kdop10x/10y/10z/18/26 (mesh.add_kdop_collision or the generic mesh.add_simple_collision), convex hulls (mesh.auto_convex_collision). mesh.set_collision_primitive edits one primitive numerically; convex hulls cannot be edited that way. mesh.copy_collision clones a whole setup onto another mesh, and mesh.get_collision_json / mesh.set_collision_json round-trip the aggregate geometry as text.

A prop built from nothing (UE 5, GeometryScripting)

mesh.gs_info {}                       // confirm the plugin is enabled
mesh.gs_pipeline {
  "primitive":"box", "dimensions":{"x":200,"y":200,"z":40},
  "ops":[ {"op":"translate","vector":{"x":0,"y":0,"z":20}},
          {"op":"recompute_normals","amount":45},
          {"op":"simplify_percent","amount":0.8} ],
  "folder":"/Game/Props", "name":"SM_Platform", "collision":true }

mesh.gs_pipeline is the one-call version. The individual steps also exist: mesh.gs_create_box/sphere/cylinder/capsule/cone/torus/plane/stairs/ramp create a new asset, and mesh.gs_boolean, mesh.gs_simplify, mesh.gs_transform, mesh.gs_mirror, mesh.gs_recenter_pivot, mesh.gs_weld, mesh.gs_fill_holes, mesh.gs_remove_small_components, mesh.gs_voxel_solidify, mesh.gs_voxel_morphology, mesh.gs_flip_normals, mesh.gs_recompute_normals, mesh.gs_set_material_ids and mesh.gs_combine edit an existing one. Every modify tool takes inPlace (default true) or a folder + name pair to write a copy instead. mesh.gs_measure returns triangle/vertex counts, surface area, volume and bounds; mesh.gs_generate_collision_from_mesh produces simple collision from the geometry itself (box, sphere, capsule, convex, swept_hull, min_volume, level_set).

Project-wide clean-up

mesh.audit                  {"folder":"/Game","maxTriangles":50000,"minLods":2,"onlyOffenders":true}
mesh.find_without_collision {"folder":"/Game/Props"}
mesh.batch_auto_collision   {"folder":"/Game/Props","kind":"box","onlyMissing":true,"dryRun":true}
mesh.batch_auto_collision   {"folder":"/Game/Props","kind":"box","onlyMissing":true,"dryRun":false}

Every batch tool defaults to dryRun: true: run it once to see what would change, then repeat with dryRun: false. The family is mesh.batch_set_lod_group, mesh.batch_generate_lods, mesh.batch_set_lightmap, mesh.batch_set_nanite (5.0+), mesh.batch_set_build_settings, mesh.batch_rebuild and mesh.batch_auto_collision. The read-only finders are mesh.find_high_poly, mesh.find_without_lods, mesh.find_without_collision and mesh.find_duplicate_geometry.

Skeletal meshes

mesh.sk_get_info first, then mesh.sk_list_bones, mesh.sk_list_morph_targets, mesh.sk_list_sockets. To give a character physics:

mesh.sk_create_physics_asset {"mesh":"/Game/Chars/SK_Hero","folder":"/Game/Chars",
                              "name":"PHYS_Hero","geomType":"sphyl","assign":true}

mesh.sk_regenerate_lods and mesh.sk_remove_lods need UE 5 (4.27 has no scripting entry point for them and returns E_NOT_SUPPORTED with a hint); the reduction settings themselves (mesh.sk_set_reduction) can be written on both engines.

Gotchas

Rebuild cost. Tools that change build/reduction/UV settings call PostEditChange(), which rebuilds the render data. Several of them take rebuild: false so you can batch the changes and finish with one mesh.rebuild. Triangle counts in a reply come from the built data, so they only move after a rebuild.
Engine content is read-only in spirit. Duplicate first: mesh.duplicate {"mesh":"/Engine/BasicShapes/Cube","folder":"/Game/Temp","name":"SM_Copy"}, then edit the copy.
Nanite vs LODs. A Nanite mesh ignores the LOD chain at render time but still uses it for the fallback mesh and for collision. Do not delete the LODs of a Nanite mesh that also uses use_complex_as_simple collision — mesh.validate flags that combination.
Lightmap UVs. coordinateIndex must point at a channel that exists, or the lighting build reuses channel 0 (overlapping UVs). Either turn on the generator with mesh.generate_lightmap_uv or create the channel yourself with mesh.add_uv_channel + a projection.
UV editing needs source geometry. mesh.copy_uv_channel, mesh.set_uv_tiling and mesh.flip_uv_v work on the mesh description, so they refuse meshes that only have render data (E_NOT_SUPPORTED). The projection tools (mesh.generate_planar_uv and friends) work anywhere.
4.27 differences. On 4.27 the kit goes through UEditorStaticMeshLibrary (EditorScriptingUtilities, already enabled by the plugin); on 5.x through UStaticMeshEditorSubsystem / USkeletalMeshEditorSubsystem. Nanite, Geometry Script and the skeletal LOD regeneration tools simply do not exist on 4.27.
Geometry Script must be enabled. The mesh.gs_* tools carry RequiresPlugin="GeometryScripting": if the plugin is off they are not listed and calls are refused with the plugin name. mesh.gs_info always answers and tells you whether it is enabled.
mesh.merge needs an editor world. It merges through temporary actors, so it is refused with E_EDITOR_STATE when no map is open. lodSelection: -1 merges all LODs; a value of 0-7 merges that specific LOD and is required if you also want mergeMaterials. The engine's merge utility picks its own asset name (/Game/F/SM_Merged would become /Game/F/SM_SM_Merged), so the tool moves the result to the exact folder/name you asked for and always returns the final object path in mesh; anything it could not do lands in notes.
Material slots. mesh.remove_material_slot refuses while a render section still points at the slot; move the section with mesh.set_section first.
