I am getting consistent insta-crashes in zBrush when I use a curve brush on a tool with a texture from a uv map. It’s very frustrating trying to work around this. Is this a known problem (or a feature)?
I’ve not come across that before. Is this just with a particular mesh?
Thanks for your reply. It seems to be a real bug as far as I can tell. I’ve been able to reproduce it on different systems. Take a primitive, a plane3D for example, unwrap it and then create a new texture map from uv. A few strokes with a curve brush will kill zBrush.
Do I get a zCookie?! 
@ neovieux
Tried your steps and no crash yet…
OS?
What version of ZBrush? Including service packs…
that’s weird, it happens consistently for me on two different systems.
I have zbrush 4R7 P3, 64 bit, windows 10, intel 4770k with 32Gb memory
