Today I had to export this model to obj, it has 796k polys, and I had to wait 12 minutes, I have i7 and 28 GB RAM. C4D or Max made it for about 45 sec.This and other speed limitations turns Nvil into lowpoly modeller, becouse work with high poly models is VERY VERY HARD
There's a scene there are two hidden mesh of 3d cout,

steve, on obj export, objects are duplicated then combine into one object. The data will be further modify for exporting. The duplication will consume memory. When combine, it does not merge meshes, so it consumes little memory and takes little time. The problem I found is I used a bad algorithm on polygon sorting.
