Hello ZBC, I have customized 5 existing brushes to ease my hardsurface sculpting.
I have to mention that I am using a mouse to sculpt(not the easy way I know).
Thanks to the dpi (wich i set to 400) and the lazy mouse option usualy set to 30 i’m able sculpt rather quickly.
The helmet is concepted in about 15 minutes, without out these brushes it would have taken me a lot longer.
Hope these are helpfull, if you have any questions, or want the helmet.ztl ,drop me a email.
