Anybody have a problem like this? I just used a sample of the HDRI file from Paul Debevec's site (st_peters_probe.hdr) and translated it via HDRShop to a longitude/Latitude map. The problem is that I get this artifacting (circled) when I render. This may be caused by my settings not being precise enough, but I thought I'd sound off anyway. Suggestions? The image shows my current render settings as well Ken
