This Video shows you how to decompile (only) Valve .mdl binary models into .SMD, .VTA, .VRD and .QC formats required for import into Blender using Zeq Macaw's Crowbar (Source Modding Tool).

It doesn't matter if the model is a prop, character, vehicle or animation model and it doesn't matter what Valve Goldsrc or Source(1) game it comes from. If it is a Valve Binary .mdl model, the process is the same.
