[Urgent] Getting a mesh emitter to fade out

I’m having trouble getting a mesh emitter to fade out even with a vertex color node in it’s material. I also think I need a particle color node in order to control the color. Can I have both and still have the alpha fade out?

in ue4 you need a particle color node, not vertex color node. (I still make this mistake occasionally)
Also, just multiply the output of the particle color node with whatever is controlling your opacity.

You can have both,but you’d need i.e. a dynamic parameter node to separately control the vertex colors (if you want to control them dynamically)

Thanks man, you’ve been really helpful to me lately at an invaluable time.
Are you saying that in order to control both color and opacity of a mesh emitter properly, I need to multiply a dynamic parameter node with vertex/particle color nodes?
