I need more info on those: 3. The model should be sculpted and textured in 3D-Coat.
4. Poly-modeled in other 3D modeling software is allowed.
If I get correct, I can poly-model my vehicle for example in Maya, but must finish it sculpting in 3D-Coat + texturing too? There is no way to model/sculpt in other apps, but make textures in 3D-Coat for this competition, right?
