Single animation controller for multiple material parameters

[rpardridge]

Edit: I think I figured out how to do this with the Reaction Manager

I would like to setup something where I have a single controller that affects multiple material parameters.

For example, let's say I have 5 different materials and I want to animate the Emission amount. I can do this by animating all 5 individually but that is a bit time consuming, especially if I want to change it around later.

What I am thinking is that I would setup something (I guess via script?) where I can just move a dummy object along the x-axis, and the script links the x-axis position difference to each material's Emission amount. Then I can just work in the curve editor on the dummy object x-axis position animation, and it will propagate to all 5 materials' emission amount.

I am guessing I need to do some scripting to make this happen, or maybe there's a simpler solution already available?

Any help appreciated thanks!

You can do this pretty easily with wire parameters dialog (Animation>Wire Parameters>Wire Parameters Dialog) by wiring the X position of the dummy to the Emission amount of each of the five object's materials.  As you can see below I added a scaling factor of 0.01 to control/expand the range of x position influence on emission amount.  I  also set each material to a different emission color.  You can also set different scaling factors for each material if you want to vary the influence for each material.

In Slate Mat. Editor open "Controllers" group, "drag" Bezier Float and connect it to all mat. Emission (amount)

Or...

In Curve Editor copy one material Emission Ctrler and paste it as instance  to others
