Well i got a situation where i need to switch cycles materials for several objects.
So i made for each of those objects a cycle shaders that consist of 2 variants.
A mix shader value can be set to switch between the two shaders.
One material look is more alike a schematical overview, while the others is normal real material view.
But since i have to switch manny objects between those two materials.
I wondered for animation would is it possible to only use one value that affects them all.
