While sculpting I ran into this issue:
Both sides got very close to each other. So while there is a hole on one side it looks OK on the other.
When trying to fill the hole, in this case with clay strips, the hole gets filled on one side, but it makes a new hole on the other.
From another perspective the entire part of the mesh has collapsed on itself.
Is there any way to give thickness to this part again?
It seems as if the vertices became stuck to each other.
Thank you very much for any ideas!
