Using Dynamic Material Parameters with Decal Component Renderers in Niagara

Is there a way to control paramaters of material instances which are used by Decal Component renderers?
Im trying to set the opacity in the material from the emitter (or even the Actor, which has the Niagara System as a Component). I also need to be able to do it for each particle individually, which I’m trying to use the NormalizedExecIndex for.
Or is there another way to do this? I cant seem to set the decals opactiy directly without using the isVisble flag, which would make fading impossible.

Any help is appreciated! :slight_smile:

You will need to use a dynamic material instance. The documentation mentions them a bit here
There is a blueprint function you can call on the decal component to generate a dynamic material instance.
