I'm using a clip studio as a drawing tool, but I only bought it for brush-down purposes, so I just said, "Draw!I feel like I've only been using it. I used to erase the areas that need to be soft, but I just found out that there's a brush concentration control. ^^! Thank you. The number keys don't work in this tool, so I pressed several keys, and the Ctrl+[Key] key makes it 10cm lighter and darker. If you don't know who's using the same tool, I hope it helps.😉
