Regarding the splotches, don't use an IBL with an image map. Been messing around all morning. Not done testing, have to leave for a wedding in a few. But IBL's are giving me heavy splothes when using IDL. Also higher the IDL bounces seem to cause fits too. Try using the D3D render controls found in the partners script folder and lower the IDL bounces compared to the RT bounces and see if that helps.
