Is there a Grease Cut (Sculpt Tools UI Addon) functionality in Blender 2.8 or an updated Addon for this Blender version? As pointed out here, the old Sculpt Tools UI Addon is no longer compatible with Blender in version 2.8 upwards.
Not yet, but be patient Pablo Dobarro is working on something similar:
Not Grease Cut but Line, Box and Lasso Cut.
Thank you, spikeyxxx, I can't wait to see this in Blender: The preview already looks great 👍. Somehow reminds me of my butcher😁. But, is there a workaround within Sculpt Mode or do I have to separate parts in Edit Mode?
Probably the best result is to use Booleans in Object Mode. Apply and then back to Sculpt Mode. Might be an other way, that I am not aware of.
