I am getting some problems rendering in the IPR:
I have tried it and the render got stick in the Building Octree stage.
My width are in the order of e-1 and I am not using rayttracing at
all, just micropolygon render with a spot light without shadows.
I have tried to add the vm_kdememfactor render attribute but doesn't helps.
Seems that for any reason the IPR is trying all the time to make the
octree and it stucks on this stage.
On the other hand rendering to Mantra is rally fast
