load_mesh_network()

std::shared_ptr< Nodes::Network::MeshNetwork > MayaFlux::IO::IOManager::load_mesh_network	(	const std::string &	filepath,
		TextureResolver	resolver = nullptr
	)

Load a 3D model file as a MeshNetwork.

One MeshSlot per aiMesh. Per-slot diffuse textures resolved via resolver. Null resolver uses the default: ImageReader::load_texture relative to the model file's directory.

Parameters

filepath	Path to the model file.
resolver	Optional texture resolver.

Returns

Populated MeshNetwork, or nullptr on failure.
