I think it is a big advantage of dyntopo to be able to sharply sculpting a part without subdividing the entire mesh.
However, when rubbed with a smooth brush, there is a tendency to leave traces near the boundaries of the different density topologies.
I have marked it with a red grease pencil on the attached photo.
How can I make this place a natural gradient?
Also, I would be grateful if you could give me the correct order or tips for multi-density work.
