Light passes from embergen for composting

so i have a scene there is a character, and there are emissive particles removing around him , everything looks so good, but I want render out the light pass, which is generated by particles on the character, how do I do it ? , note: I have tried rendering out emissive shapes but those are very much jittery and cubic-like big pixels

Hi there,

Sorry for the late reply, but can you send over the EmberGen file you’re using. I can see if i can find what the issue is.
