Need help with gmod types of files!

What are the file types that are vtx,vvd,and phy. Also how do you make them?

I’m pretty sure those are all model filetypes, common throughout Source games (and maybe other game engines too). You need a modeling program to make them, I’m sure.

but do i need them to make a model and if i do how do i make them exactly?


Oh nvm Found out thanks kung fu
