CS2 Physics Data Extractor

Extract physics collision data from Counter-Strike 2 maps (both official and workshop maps).

What it does

This tool finds your CS2 maps and extracts their physics collision meshes in multiple formats from world_physics.vmdl_c files. Choose between .tri (triangle mesh), .vphys (physics data), or both formats. Useful for Visibility checks on external cheats.
