Sorry Sam not clear there. I triangulate in Carrara. Lith is used for test for missing ones, but I don't triangulate in Lith because I find Poser doesn't like how Lith does it's triangulation.

Though yea I also find the whole triangulation thing a confusing PITA. If I want to unfold a model in Pepakura (turns meshes into paper models), triangulated models can sometimes confuse it. Yet Slice for Fusion360 (used to turn meshes into real world models), and my 3d printer software, doesn't seem to care if a mesh is triangulated or not.

Pinky - you left the lens cap of your mind on again.
