Thanks dandelO for explaining it here,
I somehow thought it was already somewhere.
Dune, tell me how to create a handler node and I´ll try it. I have no idea where to look.
If it works this would be a great inclusion to my update, which is meant to include more realistic proportions and a real restriction to a ring, because in many settings the "forcefield-effect" gets quite strong.
Thats what I like about TG, you can use a piece of someone elses work, go on with it and create something new.
Of course this is true of all artforms, but here it feels more like cooperation than plagiarism.
Therefore I hope to make my rainbow more useful.
Best regards,
Jan
