Hi
I've followed the advice in the splotches pdf to try and get rid of the problems you can see in the attached image around the ceiling raft and on the column. I've set indirect caustics to none and visible to indirect rays un-checked for the ceiling material. I'm rendering using interior best but still having problems. Any suggestions? I've attached the dgn.

Within MicroStation 08.11.09.459 there is a new optio: Irradiance Smoothing. This setting is in the Global Illumination tree of Luxology Render Settings dialog, Advanced tab. When you bring up this value Splotches will be gone.
