I cant figure this one out. After Re-activating my zbrush (I opened up a UI from a previous version and it asked for activation again) Zbrush 4 r4 (as well as R2) keeps constantly crashing! I get within 10 minutes of working and then it hangs and blips off.
I cannot think why. I got IT to re-install, that hasnt fixed the issue, still crashing. I’m starting to think it could be my ztool, though I have never heard of a ztool crashing the program. Really frustrating. Has anybody come across this issue?
