Thanks once again! I have a few reports from this last project (a major animation run) and have been to their mantis page in days past. Most often I hear from Richard Hastletine; the man gets around!  Anyway, I work with just the bounding box but the shader idea had never occured to me; makes perfect sense though! Scenes that often throw a fit are Tomalin-sets like Sacrement that are major resource hogs in both Studio and Lux (8.47GB in Lux the other day!) or ones where I've got dozens of little props. Wah hah! 

Just a side note, the only thing that really attracted me to the Titan was that larger 6GB allocation of memory and the higher CUDA cores count, which would come in handy for GPU rendering. I later learned that Lux happens to work much better with 79xx series but the lack of driver support scared me off. Tit for tat I suppose...
