A VTX file cannot be converted in isolation. Without the MDL, the geometry has no skeleton. Without the VVD, the indices in the VTX point to empty voids.
Converting VTX to FBX is not a "drag and drop" operation; it is a . You need the full set of Source model files, the Crowbar tool, and a middleman format like SMD. vtx to fbx
Yes, the .vtx file is useless on its own. It contains the Level of Detail (LOD) meshes and the strip groups, but it relies on the .vvd for base vertex data. Trying to convert a lone .vtx file is like trying to drive a car with wheels but no chassis. A VTX file cannot be converted in isolation
When you import the SMD into Blender, you will see grey geometry or strange pink meshes. VTX files only store texture names (like my_weapon.vtf ), not the actual bitmaps. Converting VTX to FBX is not a "drag
