here
but i have made a small discovery that maybe someone can explain
I decided to download MeshLab because it can open the .ply files that Reality exports for Luxrender
because i just needed to see if there is anything i can find that might be causing this issue
I threw in a primitive cube into Daz for this test

as you can see here its Just the cube, 6 faces, 8 vertices
and i had set only the IBL on with no image, just white and a camera to run the scene

and ofcoruse this is what it produced when run though Reality 4

and this run though Reality 2

and this is what the cube looks like in MeshLab after the export
it is divided in Loop 1 level
which doesn't seem to be the problem
But check this out
On the right of the program lists the Vertices and faces

"cube_8" is the ply exported by Reality 4
and "cube_cube_Default_2" is from Reality 2
but R4's cube has 18 vertices on the now 12 faces
while R2's cube has 24 vertices on 12 faces
i'm not sure where these vertices are coming from
8 to 24 makes more sense if each corner now has 3 vertices on top each other
but 8 to 18? that's 2.25 times more vertices
that's 2 per corner plus 2 just...Some where?
