The irony of that battle rifle, its the beta battle rifle anyways… Even if you do import into gmod its still gonna show how low poly it is even with out the normal. The FP battle is much better and is not optimized and good for world models. Especially with the real normal map heh.
For Doom 3 models if you want to extract it your self or if anybody else wants to. There is pk4 files in C:/…Doom 3/Base. Open it with WinRar and extract the md5’s were ever they are (I havn’t done it in a long time).
Go there and search for what program your using which is 3ds max probably and the script for it. For 3ds max put it in your Scripts folder and done. Just load it up and import it in.
I think bitmaps are in .dds format in the pk4 files…yeah they are.
