I am not able to sculpt properly in the middle of my mesh. Around it I use Dyntopo of 50 and it works fine but as soon as I get to the middle it does almost no changes whatsoever.

I cant figure out what is different about that part... It looks diferent, but that might be because its esentially flat surface...

Originally the mesh was 2 separate meshes , but I merged them by selecting each edge and filling (pressing F). The result was the mesh you see now and the middle part is the filled regions.

Things I tried:

  • Apply all transforms
  • Clear sculpt mask data
  • Clear split normals data
  • Increasing dyntopo
  • Remove sharps
  • Toggled flat and smooth surface

EDDIT: here is blender file with just the problem mesh: https://pasteall.org/blend/3a8c1a0fe39e49a7960bdf74ddfda235

    $\begingroup$ you need to recalculate the normals (in Edit mode, select all and press Shift N), maybe it's your problem here? $\endgroup$

  • $\begingroup$ Yes that was it ! I feel so stupid now... There are so many little things to keep track of and this one completely escaped from my head. Thanks allot for the help. $\endgroup$ Oct 10, 2021 at 18:39
