I have a .obj model, a .mtl skeleton, and a .png texture. How can i make it a player model in garry's mod

So as the title says, i want to port a model, skeleton and texture to source. I’ve looked up a lot about porting it and i found a couple of ways (which i tried) and failed. I was not able to try the 3ds max way because i could not get the installer to work; kept giving me some error.

Download to files if you want them: https://drive.google.com/file/d/0ByL6yz7-761CbE5VOG5XQlVMLUE/view?usp=sharing

If you don’t mind my asking, what was the error that you were getting with your 3DS Max installer?

I’ll go download it again and find out, not sure atm.
Also, i can get the model into maya with the skeleton attached to it if that helps at all.

Now it wont even let me open the installer lol. Anyway, error:

The mtl file stores he texture coordinates for the model. On league of legends modding community there’s a tool to import league models in 3d max and 3d maya with bones, you can use that to get the proper rigg.

Ok, so i can’t use 3ds max. How can i make the model go from maya to garry’s mod
