bagginsbill, I think that fix only applies to windows users. I'm on a mac (tiger) and I couldn't find any lines with col or column in it.

However, my problem was resolved after reinstalling the patch. When I did that, I let it delete my previous settings, which the first time, I had told it to keep them.

As for redownloading the scripts, I got them from daz, and there haven't been any updates there ( I did redownload from their site, and reinstalled it, but that didn't do anything). I didn't see anything on the physics-calc site about updates for the V4 realism shader. Am I looking at the wrong site?

PilotHigh, my mac is  an intel mac pro, and my lights are the same as they were before. I haven't actually noticed any slowdown in renders either, but the texture loading seems to be annoyingly slow. I did notice that because my settings had been reset, I had to fix my preferences to use 4 threads. I grabbed it so I could see rsr thumbnails, and was very happy with that part working:P
