I was trying to follow this tutorial made in Blender 2.71.x but I haven't figured out how it can be done in 2.93.x yet. He pulls out the self intersecting geometry but when I try and do it, it says no intersections found.

His example:


My example keeps saing no intersections found.


The video tutorial / section I'm trying to follow is. @1:16 https://youtu.be/-rwvxusuJXU?t=81

Found a work around fix for intersecting faces and internal geometry, this may help someone else.

The 1st image is the original image with overlapping faces / edges

The Fixes:

The 2nd image uses the Mesh boolean node with Union.

The 3rd image uses an "inverse mold node"
