I have a quick question about v4, I'd like to test it but I'm only using the trial for v3. I see a lot of meshes that have nice quads, if I model something from scratch in Moi does that mean it can export all quad meshes? Or is this kind of export only possible when a polygon mesh is imported in and converted? Sorry, it's a bit of an odd question I guess.
