Does anyone know how to fix it…
Parameter change did not affect anything.

Ashif Ali (CGHow) has an example in his " Decal Renderer in Unreal Engine 5.2 Niagara Tutorial" that solves that issue by packing values into the Decal Color node, the way would normally use Dynamic Parameter node, you just need to control it through Make Linear Color so you can access each channel separately. It’s pretty slick.
I’m having the exact same issue. The dynamic material parameters aren’t working. How did you get that material parameter inside of Niagara? I don’t see an option to add it.
You can see the Image That I uploaded.
I think It’s very clear.
But, this solution is not good
This doesnt work, it only allows for system or emitter variables. Atm 5.5.1 decal renderer can only be used with static materials, particle color doesnt work either (which by the way you have to add as DecalColor in the material not Particle color but alpha doesnt take into account emissive).
I am not sure what was the though behind this broken and convoluted setup. Probably the same behind the complete lack of documentation and set untested features as “production ready”.
