I started with Poser 3 well more than 15 years ago. I have seen a lot of new things come and go. I not the biggest fan of new. Whenever something new comes up (ie dynamic clothing, indirect lighting, ambient occlusion, and ton of others), I test to see if it will work for what I want. I size it up on it's own merits. Some are good and some are not so good. I fail often but I learn and go on. I feel I have become a better artist by trying new things. At the end of the day, that's all we can do.

I have only one primary runtime, that's probably why I was not able to reproduce the issues. Before Poser 8, I would copy my old runtime into the new one. Now, I just point Poser at the old Poser 8 runtime and keep filling that one. I install all my DAZ Studio/DSON to that runtime as well. That probably explains why my runtime is over 490GBs.

I hope clearing the cache and setting the runtime helps.
