I allow myself to tag @DavidRutten for this question. I’m sorry David, I tried like two nights to understand why this renders out blue, but no success. I tried the changes from Custome Node Color? - #6 by DavidRutten but had no success. There must be a ton of useless snippets in the code and I understand a little more every day, but this blue canvas thing is driving me nuts!

is it correct that I need to render the canvas with base.Render and all the elements (in this case a button only) on the canvas with capsules?
thank you

Ben
