I'm evaluating Lumion right now. It definitely doesnt like ngons. It is not handeling the scale properly. I've seen a couple others mention it. I may just go with asking them about bringing in the objs, because you already have that pretty well rounded. They "DO" point to autodesk alot, because of max and revit and such..... I may consider Maya and Vray too because they have impressive output. But the cost :o and also not sure about the curve. Also, that impressive output may be from highly skilled users! :o

Lumion seems like the best alternative for me, but I will need a new computer too.. They dont like my quadro card. I'm bouncing around looking right now.

Thanks.
