This contest interests me, however, say I use Silo (polygons all the same, just a tad faster with Silo) for the modelling or Zbrush for the detailing/texturing, but I UV map and render in Maya, would that get me disqualified?

Don't know if I'd be willing to limit my arsenal really.

But Photoshop is still in right? It's technically an outside app and technically you can texture inside of Maya.
