6. Activate the Add-on

This Add-on works only one Blender 3.3 Beta. It is a Pre-Release.

Do not forget to deactivate the Original Influence Objects Collection for Renders.

Side Functions:

Apply All Visible Modifiers.

A Simple Self Intersection Remover.

Limitations:

Objects with self-intersecting will have some of the effects applied to those areas. (I used a modified version of the monkey head; usually, these objects do not work)

The Add-on has an essential clean-up function for these objects, but this produces sometimes Non-Manifold Meshes, which do not work with the Mesh Boolean.

The Add-on has a less performant for this by the Weld option through the Less Optimized Boolean, but I recommend to not use Non-Manifold Meshes.
