Model Edit

Goal: inspect a character model (Lightning, c001): its meshes, materials and textures. Then render it, and edit it through a glTF workspace.

Prerequisites

• A game open (First Run and Game Setup).
• DXVK and a GPU driver with Vulkan 1.3 support for the game-shader preview (Installing). Without them, the Fallback (wgpu) renderer draws an approximation.
• For editing: a 3D tool that can round-trip glTF (.glb), such as Blender, and an image editor.

Steps: inspect

1. Open Models in the navigator and pick chr/pc/c001/bin/c001.win32.trb (Ctrl+K, then type c001).

2. The viewport draws the model with the game’s own shaders when Renderer is Auto or D3D9 (game shaders). The status next to it names the device.

   • Toggles: Lights, Env map, Alpha passes, Backface cull, Borrowed textures.
   • Views: Bind pose, Wireframe, Bones, Sockets, Bounds.
   • Studio chooses the light preset.

3. The right column has these panels:

   Panel	Shows
   Meshes	Each mesh with its material, vertex and triangle counts. Hide, reorder (↑ ↓) or delete meshes.
   Materials	Shader parameters (PRAM).
   Textures	Each texture, to view or replace.
   Skeleton	Joints.
   Motion	Play clips from the model’s motion packs.
   Effects	VFX attached to the model.
   Import	The import report (see below).
   Output	The model’s files.
   Diagnostics	Problems found reading the model.
   Stats	Counts and sizes.

4. Render… writes a PNG. Diff compares your edit with the original.

Steps: edit through glTF

1. Choose Export for editing. CrystalWorkshop writes a workspace to <game>/ff13_studio/workspace/models/<game>/<archive path>/. Open folder opens it. The workspace holds:

   File	Edit it?
   model.glb	Yes
   textures/*.png	Yes
   model.ff13.json	No (the sidecar)
   model.obj	No (inspection only)
   manifest.json	No

2. Edit model.glb:

   • You can change: vertex positions, normals, UVs, colours and skin weights (with the same counts); material parameters in extras.ff13.params; joint rest poses; sockets.
   • You can also delete or reorder primitives (meshes), and edit a texture PNG at the same size.
   • Keep the _FF13_VID attribute and extras.ff13.key when your exporter allows it.

3. Choose Import (dry run). The report rates the import:

   • Tier A: the change patches the existing model safely, and Apply stages it.
   • Tier B: adding vertices, triangles, materials or bones is not applied yet.
   • Rejected: for example, a stale workspace from before another edit. Export again.

4. Choose Apply. The model becomes a pending change.

Result

The Changes page lists the model’s .trb and .imgb. Export them with Simple Mod Export.

Undo / revert

Undo, Redo and Revert are in the model toolbar. Revert returns the model to the game’s original. The workspace folder stays until you delete it.

Known limits (Experimental)

• Model writes for XIII-2 and LR are not verified in game.
• XIII-2 and LR background blocks borrow textures from other blocks, and the preview shows them as borrowed.
• Only Tier A imports apply. Tier B changes are reported but not written.
• New motion packs are XIII only.
