I know this is an old one, but I was hoping it would have been fixed in 2010 sp0: I have an older assy that I have opened in 2010. There are dozens of appearances called "color1", "color2", etc. in the render manager. I delete them, add my own appearances, save, and then they all come back.
Is anyone else still seeing this? I swear: between problems like this in PW and the lack of functionality in PV360, I feel like SW no longer offers a viable rendering solution. 2011 and the new improved PV360 can't get here soon enough!
Arrghh!
