If your VTX file is from a Source Engine game, it cannot be converted by itself. It is part of a model package that usually includes .mdl , .vvd , and .vtx files. To get this into an FBX, you will need to decompile it first. Step 1: Decompile with Crowbar
Legacy conversions often cause polygon normals to flip, making the model look inside-out or transparent in game engines. To fix this in Blender, enter Edit Mode, select all faces ( A ), and press Shift + N to recalculate normals outside. Final Thoughts

If you have a library of 1,000 Source Engine models (think Garry’s Mod addons or Team Fortress 2 cosmetic packs), manual conversion is impossible.
I can provide highly specialized scripts or tailored steps for your specific pipeline! If your VTX file is from a Source
is the industry-standard decompiler for the Source Engine. It is a free, open-source tool that reverse-engineers .mdl files back into StudioMDL (SMD) or DMX files, which can then be imported into Blender.
Developed by Kaydara and now owned by Autodesk, .fbx is the universal language of the 3D industry. It is an interchange format that supports: 3D geometry (meshes, vertices, polygons) Material textures and maps Skeletal rigs and bones Complex animations and morph targets Camera and lighting data Step 1: Decompile with Crowbar Legacy conversions often
Always remember to back up your original asset directories before initiating decompilation, and keep your texture maps organized alongside your newly minted FBX file for a seamless import into your engine of choice.
While the process is technical, it is entirely deterministic. With the tools listed above, any 3D artist can successfully convert VTX to FBX and breathe new life into old geometry.
