Struggling for 3 hours to fix a glitch in Blender.

Finally finding the checkbox that makes it work as intended.

Reverting back to a previous version of the models from before I messed up who knows what with all my trial and error.

What I thought is the solution does not work on second try. 😐

(Of course I did not save a copy of the version with the fix to see what else I might have changed there.)
