I was thinking of a port because I’m 99% sure that the models don’t use Valve Texture File (.vtf) and Valve Material Type (.vmt) files, which are the texture definition files required for use in Source Filmmaker or any Source Engine utility/game.
No clue if the model is a .mdl file but if I’m gonna get the U3 models in SFM it’s gonna have to be ported in.
I’ll try the SDG Wiki modding section as well, thanks.
