I have a project where I reuse the same material for multiple things. So, I use node groups; saves a lot of trouble - at first!
Up to this problem I have with node groups:
In 1 you can see, that the logo (white text) is on a black background. This black background should be a node group (and certainly not black).
Here is the Logo Overlay node group:
If I put the node group "ultramarinblau" into the Logo Overlay node group, it does not work!
Only if I add the "ultramarinblau"-node group directly into the Logo Overlay node group, it works:
This behavior is not desired. I'd like to reuse my Logo Overlay node group multiple times with a different node group-input.
What am I doing wrong? Or could this be a limitation of Cycles node groups?
Any ideas are appreciated!
