Help carving relief out how can I

Hi I just have been having trouble with best way of taking this 3d model I made with a depth map into a better model. There are areas it’s like I need to just subtract clay or model from but everything just seems to pinch or pull from elsewhere . I feel like I need to chisel or scrape away I tried downloading some extra tools but still struggling.

My initial thought would be that for a model of that detail level you only have 163k vertices. It likely doesn’t have enough vertices to be able to sculpt without pulling for here and there because the vertices are large.

However, without more information, that’s just a guess. Maybe you can provide more information, screenshots with the wireframe turned on, etc.? Or maybe someone else will have a better idea?

Try voxel remeshing with a quite high value, and the issue should not persist…
