Converting VTX (Vertex Animation Texture) data to FBX is not a standard "Save As" feature in most 3D software because VTX usually refers to a real-time animation technique (baking mesh deformation into textures) rather than a standard rigging format.

Source Engine models use up to 3 bone weights per vertex (configurable, but usually 3). Converting VTX (Vertex Animation Texture) data to FBX
