build workspace

src/build/workspace.ts — Workspace creation & texture import

Blockbench-dependent layer. Generation creates a new standalone workspace (model tab) instead of dumping output into the current one: the name comes from the wizard, the texture resolution = the shared texture size of the three parts, and the parts' source textures are imported there so the assembly layer can resolve cube-face texture references to real Texture objects.

createTrackWorkspace(format, name, textureSize, textures)

Creates the output workspace and imports the part textures, returning a "source texture key → Texture" map.

• creates the workspace with the given format — pass 'free' (the free model, the only format that can hold mesh groups) when a part has mesh groups, otherwise Java block/item model
• sets the workspace name and texture resolution
• removes the new workspace's default blank texture, then imports the parts' source textures (deduplicated by source)

Throws on failure (invalid format / cannot create); the caller surfaces the message.

export function createTrackWorkspace(
	format: ModelFormat | string,
	name: string,
	textureSize: [number, number],
	textures: SourceTexture[]
): Map<string, Texture>;
