i accidentally flooded my sculpt brushes with copies, so now i’m wondering can you delete them while in a project? If then don’t worry.
import bpy for i in bpy.data.brushes: if "." in i.name: i.user_clear() bpy.data.brushes.remove(i)
This script will remove all the brushes that have a “.” in their name (As all of copies if you have not renamed them).
