It’s all in the title, I need to be able to set the opacity over time of my Niagara emitter on mesh renderer.
If anyone has any insight that would be greatly appreciated.

PS : If I find a solution, I’ll post it here

You could use DynamicParameter node in particle or mesh material and use any channel to Opacity, and then in niagara add a DynamicParemeter module in the Particle Update and set this dynamic parameter as “Float from Curve” and use “NormalizedAge” as CurveIndex.

Or you could add a Color Module in the ParticleUpdate and set it as “Color From Curve” and use alpha channel to set opacity.

Found my problem ! I wasn’t using the ‘Particle Color’ node on my mesh’s material. Just needed to plug the alpha chanel (with a Lerp)

And after that use ‘ParticleUpdate’ ‘ScaleColor’ ‘ScaleAlpha’ ‘float from curve’
