Which does vray peform better with or should I say have fewer problems with?
Tony
lol…is there actaully a difference???
If I had to guess, I would say Vray converts e.polys to e.mesh and then renders them, so there souldn’t be a difference at all…vlado?
P.S.: large e.polys are a pain in the a** in viewports so I always have a turn_to_mesh mod on them. (that means: I can’t really tell) 
when it comes down to freaky faces, epolies have never given me probs in vray unlike e-meshes.
I generally use e-polys for modeling but I thought perhaps I was missing out on a performance boost if I converted to e-mesh before render.
It seems I remember folks saying a while back that it did help to use e-mesh, I guess with all the new builds since then, it makes no difference now.

it’s all the same…but e-mesh takes less ram(i think) and smaller file size…
