Modelling with Maya and SoftImage 3D?

By pure luck I got two of the best 3D modelling applications available for my Octane. SoftImage 4 and Alias Maya 4. I’m wondering if I can create models and such under either modelling environment and then export them for use in Gmod and other source games. I’m aware that for 3DS MAX at the least you need a plugin, right?
It would be really nice if I could do work on this system and not on my PC.
