blender sculpt brush not working
HeyBraza points at the remesh and dyntopo controls so your brush finally has geometry to move.
a sculpt brush can only move vertices that exist. a default cube has eight - so the brush appears to do nothing at all. adding density is the fix, and blender gives you three ways to do it.
short answer
almost always not enough geometry to push around. remesh the object (voxel size ~0.02) or turn on dyntopo so blender adds detail under the brush. if one area alone won't respond it's masked - press alt+m to clear it.
or do it yourself
- 1check the basics first: the object is selected, you're in sculpt mode, and the brush radius (f) is smaller than the model.
- 2add density the quick way: in sculpt mode open the 'remesh' dropdown in the header, set voxel size to about 0.02 m and hit 'remesh' (ctrl + r).
- 3or enable dyntopo (ctrl + d) so blender adds detail under the brush as you go.
- 4or do it manually: edit mode, select all, right-click > 'subdivide' a few times, then return to sculpt mode.
- 5still nothing in one area? it may be masked - press alt + m to clear the mask, and check 'strength' isn't near zero.

downloadcommon questions
remesh or dyntopo - which should i use?
remesh for an even base you keep sculpting on; dyntopo for detail added only where you brush. remesh is friendlier to start.
why did remesh destroy my sharp edges?
voxel remesh rebuilds the surface uniformly. raise the resolution, or use a multiresolution modifier instead to keep the base shape.
