I have problems adding more details (Blender 2.82.7) using Dyntopo.
Like the indents in the mouth, for the teeth, are suddenly not symmetrical.
‘X’ Option still on !
Also adding eye lids details and smoothing them, basically removes the action before.
Maybe, re-mesh to a lower res, fixing problems and start adding more details.
177K verts 355K Tris
But, as a first real sculpting project, I am pleased with the results. The sculpt process is clear to me.
Now I need more practice.
