^ Not sure that disabling Dynamic could help here.
Lots of wrongs here in question, will try answer some…
…5 mio. points, wouldn’t that be enough?
5 millions points is more than enough for something like human head, you can sculpt wrinkles on 2 levels lower
…Intensity of the Rake brush to 1 already…
From your screen, you set draw size to 1, not intensity
Dont think that you can work with that brush on lowest size in regular conditions
Also focal shift on 0 which is not default for this brush and there is reason for that
…zoomed in as much as I could
dont know what that means…
If your brush is too big on size 1 than you should check size of your tool (mesh) under Geometry -> Size.
Best if it’s around 2 on xyz, if it’s much lower your brushes will be to big, and vice versa
