I have been testing out importing Obj files with ngons rather than quads/triangles into Carrara6.
They seem to be fine!
I allways understood Ngons were a nono for Carrara?
Any comments from anyone?

I've built objects in Carrara with polygons carrying much more than three or four sides. The top of a cylinder, for instance, will have 16 sides (at default). Is that what you mean by "ngon?"
I do know that Carrara handles triangles best, quads well, and greater numbers of sides with less and less aplomb. But it clearly does handle larger polygons.

Carrara begins to fall apart when n > 17 or 18. Non-planars start to get out of hand.

Thanks Shonner. I had 18 in my last test--which is more that I would expect in a lot of my work so n-Gons sould be helpfull to me within your suggested limits.

Ngons are fine for certain things like house walls with windows and doors cut out of them. Ngons are bad with organic objects though when Catmull-Clark smoothing has trouble knowing the topology flow you're after, and some UV unrapping apps get confused trying to properly resize their UV maps.

Learned that the hard way, quads only for me now.
