How to set overall opacity for a particle system?

Hi There,

I have a particle system that fades particles in and out during their lifetime using the particle editor. I would like to scale the overall opacity of the system, so that I can fade it in and out as a whole.

Right now I’ve done this (I think, still WIP and untested) by adding a dynamic material instance with an extra opacity multiplier. However this approach seems overly heavy as it operates on a per pixel level and there is already an opacity blend in there that it would be nice to leverage.

Is there a way I can do this without the material instance and extra per pixel operation?
