A file stores the vertex data for 3D models used in the Source Engine . This includes the physical coordinates of the model's points, surface normals, tangents, and UV map texture coordinates. vvd to obj

To successfully get an OBJ file from Source Engine assets, follow these steps using the community-standard tool . 1. Decompile with Crowbar VVD is just the vertex data!
Converting .vvd files to .obj is a rite of passage for Source Engine modders. Remember, VVD is just the vertex data! You need to decompile the whole package (usually via Crowbar) to get a mesh you can actually work with.
