@duerer WOW I just finished reading your master’s thesis on this issue! That’s some serious troubleshooting. @spikeyxxx-level troubleshooting in fact. Perhaps this is worth reporting as a Blender bug?
You two are a great example of people willing to figure out precisely why / how something works. People like you are the reason why Blender gets better every week.
Meanwhile I will try a few times and move on to something else if I can’t make it do what I want. People like me are NOT the reason Blender gets better every week 😅
