Here is my problem:
I have a bunch of Layers, I want to behave the same way (here scaling, but I had also rotation before). My approach (as used formerly with my 3D applications) is to create a "dummy" layer, where the channnels of the other layers are linked to. For this I used the "Placeholder" item, but rendering obviously got me an error message, because the "placeholder" is intended for other use.
So my question: How do you solve such a situation the intended way?

Found the possible answer by sniffing on other peoples problems: The dummy is called "Null" here!
Unfortunetly, I cannot offer to myself the 10 points!
