Can anyone help me to determine why I'm getting purple spots in my image. I have played around with the render settings for quite a while but no matter what the spots show up. The settings are global ambience with quality boost at +4. Render settings are user defined with everything checked. Turning items on or off or increasing the antialising to 100% and subrays per pixel to the max at 64 has no effect. Turning off antialising completely will remove them, but the water and almost everything else looks like crap. Any suggestions? Thanks, Daniel.
