I am doing a cool tutorial that is from a version for 3.1 zbrush. I got to a point and it is calling for me to use Set Sel and a number for the next step. in the picture it shows those settings under Masking. What happened to those? were they replaced or moved? they seem like very useful tools, from what i can understand of their function. How do I do these operations now?
Any help would be appreciated thank you!
