@Ace_Dragon Have you seen the state of the Maya Smart Extude? It is just there to check a tickbox.
Here is a compersion between Maya 2025 Smart Extrude VS Blender Smart Extrude, note that the Maya Cube has 4x less tris than the Blender one! And still in Maya I get literally 1fps!
(Smart Extrude operation for Blender will be added to my add-on once finished)
The Maya Smart Extrude can not even handle the Blender monkey!
(Note that I will add an option later so that the extrude effect all mesh parts and not just the extrude island)
