For the mask, as in the post above by Martin, you only need to set the overlay to 1, which will set the mask to full opacity. But then for the following alongside with Kent, that is a bit tricky, since sculpting is a lot like drawing, in that you may think you’re doing the same as what you see on screen, but there’s the art part that can’t be copied like that. It’s as watching someone hand draw a super realistic portrait, even if you follow along, you wont be able to paint the realistic portrait as he is doing, because that person knows how to make realistic portraits, he’s had years and years of practice and experience. Same with Kent, he makes it look easy, but he knows how to sculpt, and we just can’t copy his skills just by watching, we need to practice a lot before we get that good.
