Sculpting tools don't seem to work unless using remesh or dyntopo I'm trying to learn sculpting but my brushes don't seem to work. The add and subtract just do their work in a general area no matter how smaller the radius of the brush is and the crease brush gives me a crease at highest power with several stroked along a already bulging crease. Help!

PS. I tried looking at other solutions but they were outdated or I wasn't able to find the options in blender.

Thanks for the answer. It works amazing. I can't reply or upvote as of yet so hopefully you will be able to read this
I was able to sculpt when I applied the two modifiers (mirror &amp; sub) and filled the holes in Edit Mode (select all + f for fill). I don't know enough about the sculpt tools but maybe brushes like crease need closed meshes. Depending on what you want to do don't expect high resolution and details without Dyntopo on this one.
