Is it possible in the sequencer to link material parameters between different actors?

[Constantinesis]

I would like to control the luminance value of a material through the sequencer.
It is applied to multiple lights meshes so I want the glass to show as turned on or off.
Is it possible to control the parameter for all of them at the same time?

Another way could be if it was possible to link actors all together just like in Blender, so a change to a parameter of an actor to be updated in another linked instance of the actor.
Is that possible?

Or by Grouping? Is it possible to change the same parameter together?

The only way I found is with the Sequencer Curves, if I select them, I can assign same value to multiple keys but its not the fastest way to do it…

You can link many materials through a “material parameter collection”
Then you can just animate it’s parameters to change many materials at once.

Inside a material you can access material collections and get their parameters & hook them up to drive nodes.

Thanks, will try it!
Does it work with material instances too?

[3dRaven]

Yes it should.
Instance also have a couple of per-Instance nodes in materials that can drive things per instance. (you can add random values / color variants etc)

Hello @3dRaven
I have created the Material parameter collection but I can`t find it in the sequencer
The only parameters that I can see are Emmissive color and Param.
My parameter is named Illuminance Level

Do I need to add or change something in the node configuration so that the Illuminance Level appears as a parameter? Thanks!

Nevermind, I found it! I had to add a specific track for the Material Parameter Collection ! Thanks again !
