Each app has its camps. C4D for motion graphics, Lightwave for all-round indie (and Star Trek), Max for corporate and games, Maya for character, Houdini for effects, and Soft for, er, lotsa high-end stuff. Just modelling? Rhino maybe. Of course, I could be wrong on the aforementioned list, but there is no one industry standard.
Anyway, try CGTalk maybe — we’re AE-centered here. 🙂
