Hello, I'm trying to understand sketching with ZBrush 4 using a Tablet PC. I have 3 questions, maybe one of you could easily answer it, please excuse my lack of knowledge.
1. Everytime I hit the Quick Sketch Button, something different happens. Sometimes I get a red plane, sometimes I get a grey plane, sometimes a black one. Also I get settings that don't seem to make much sense for sketching, for example a chessbox tile texture. How can I make sure I always get specific settings that I can choose once?
2. Is there a way to clear the sketch on the automatically created plane and start again or do I have to use the Quick Sketch Button again?
3. When hitting Ctrl+Z suddenly the plane changes from nutreal grey to a red tone, is that normal?
Thank you very much for your time!
