create_mesh_buffers()

std::vector< std::shared_ptr< Buffers::MeshBuffer > > MayaFlux::IO::ModelReader::create_mesh_buffers

(

const TextureResolver &

resolver = nullptr

)

const

Construct one MeshBuffer per mesh in the currently loaded scene.

Calls extract_meshes() internally. Returns empty if no scene is loaded. setup_processors() and setup_rendering() are left to the caller.

If resolver is provided, it is called with the raw diffuse path from each mesh's material. The returned VKImage is bound via bind_diffuse_texture(). Null resolver skips texture binding entirely.

Parameters

resolver

Optional texture resolver.

Returns

One MeshBuffer per aiMesh in scene order.
