I'm almost sure that what I want to achieve is impossible but I will give it a shot anyway: I want to make a custom brush with this behaviour:
- with first brush stroke I will add depth (Zadd)
- with second brush stroke I will substract depth (Zsub)
- with third stroke I will add depth
- with fourth stroke I will substract
- and so on -- all of this automatically of course, without holding and realising ALT key. Any chance to do this?
