I don't know if it's the textures because so far I've been sticking to many preset ones with little modification.  It's been a long time since I've used V5, maybe I just wasn't doing things too often that caused it to act up back in the day.

Thanks for the info guys.

Now it's up to learn about instancing and how not to crash it, plus deal with power consuming lighting methods.  Even with a new computer with much bigger CPU and more memory than I've ever had before, I still bog this stuff down fast.  There are a few pieces I want to do, but have to build up my skill and understanding of this software before I attempt it.
