I want to change the color of two Materials with one group node.
That's my setup:
First material (Car paint)
just a Glossy BSDF for the color inside a group.
Second material (Black strips - mask)
A Black & White mask in the fac of the mix shader. In the mix shader the Color group from first material and a glossy BSDF to change the strip color.
I assigned the first material (Car paint) to those parts where I don't want the strips to be.
And my problem is that the color I change on the input of that group don't sync with each other:
Only when go inside the group and disconnect the inputs and change the color there it is working. But then I'm not able to change the color on the right side in the materials tab inside the properties window.
It is not quite that of a problem but I just don't understand why the group inputs don't sync with each other like when I'm inside the group. What makes changing the Color for both materials at same time impossible in side the properties window in the materials tab. Maybe my setup is just wrong for the kind of result I'm looking for.
So my question is why the Group Inputs don't sync with each other? And would there be a other way to achieve the result I'm looking for?
