Centralize material parameters of several materials?

[yaschancool]

Hi,
I am working with a large space ship for VFX project. It is very complicated model with dozens and dozens or rigged parts.
Some parts of the ship need to have unique StochasticFlakesMtls.

Then these shaders must reference unique texture maps to get the underlying colors right, so I need unique Mtl nodes for each parts.

Now if the client wants to adjust the color parameters of these materials, I am kind of out of luck because I would need to go through dozen or so mtl nodes to copy and paste values..

Is there a way to program a variable or something in the slate editor to adjust all these at once?

I would really appreciate any pro advice on this.

Thanks
Jaakko

Try adding a "Bezier Float" node for value parameters and "Bezier Point3" node for colors and link it to the materials' respective values. You would need to show the additional parameters of the materials (right-click on a material in the Slate Material Editor>Show Additional Parameters). This way changing the controllers' value will change all the linked values.
