I just ran into this problem… Everytime I subdivide the polygons in my sculpt do not duplicate. It says I have 101k polygons but I only have 33k on screen.
I can’t go down subdivisions either.
Can you post a screenshot of the mesh and your Subtool and Geometry menus open?
You click ‘Divide’ button and nothing happens?
Only 1 subtool?
Make sure you clear any masks. You can hold down ‘Ctrl’ key and LMB drag on empty part of canvas or go to Tool > Masking and click ‘Clear’ button.
That fixed it. Thanks!
