There is only one file type that uses the .VISUAL_PROCESSED extension:
World of Tanks 3D Model Surface File
3D model surface file format used by World of Tanks (WoT), a war game featuring battles between tanks and other armored vehicles; contains texture information about the surface of a tank 3D model; replaced the .VISUAL format with the release of WoT 0.9.10.
You can convert WoT models to the Wavefront 3D Object format with the World of Tanks Model Converter script. The .PRIMITIVES_PROCESSED and VISUAL_PROCESSED files are required in order to create the .OBJ or .MTL file.
