Night-illuminated particles (with LM version of the texture)

This is an incredibly quiet forum, but I will try nonetheless…

I am trying to get a LM (emmissive) particle to FADE OUT in emissive color during its lifetime. I can set the color on a white LM particle, but for the life of me, I can’t get it to fade out. The same method is working on the diffuse (daytime) version particle.

Can anyone please :folded_hands: enlighten me? (excuse the pun :wink: )
