In Blender, it can be done. There a bunch of videos out there but I have not tried it myself. Blender is free and ideal for texture work.
@robert3985 , I finally pursued the PWM settings on the Saturn 4 16k ultra that you suggested. By decreasing both PWM settings I could resolve the holes in my test I posted a while back. With PWM at 135 (53%) @2 seconds with 8k resin, it would print 0.25 mm holes consistently. You can't even see them but they exist when you hold them up to the light. It also operated much cooler - ~28 vs 34 °C, and the baseplate came off easier and even had some of the holes. I could not discern any difference in the print dimensions but it needs more testing. It is getting much less UV so the exposure might need tweaking for prints. Thanks for the suggestion!
