I'll throw in another wrench. While I have shadows, if I zoom out sculpts go wonky and stay that way. ONLY if, and only sometimes, do I have a temp, partial solution. If I manually delete all my cache the problem is fixed but only until I zoom out again. More often than not , I have to completely reinstall after a manual clearing out. And, of course, the issue is back if zoom out. I wondered if it was me because the Kirstens Viewer does the same. This makes taking pictures with shadows impossible. What happened? Is there a setting I can tweek? Is there another viewer? ANYTHING?? I'm stuck with no way to take good outfit pics. I'm running a year old, high end NVidia card.
