I made this study in Blender 2.81 latest builds. Pablo Dobarro has put a lot of work on improving sculpting performance. Now, if you zoom in in a part of the sculpture, the unseen part of the model gets hidden and this improves speed performance a lot. You can also manually hide parts of the model and you will get the same result. It is very useful for adding details.
In this piece I used the new remesh in sculpt mode. Got to almost 10 million polygons. And I think I could go one step further to add even more detail. I don’t think it would crash. But I had enough detail to work.
I started with a rigged simple base mesh I did last week to get the pose, then I started sculpting asymmetrically.
Rendered in Eevee.
