If there's any features you want in StudioMDL, please tell me! Since I have a custom version of it, which is basically at Sven Co-op levels in terms of vanilla GoldSrc. I can add pretty much anything.
So for example, I may begin working on adding support for pretty much every 3D model format out there, so you can export to OBJ and be able to reference it in your QC and it'll just work.
