Is there a way to use subuv with beam data

I’m trying to make a lightning effect come out of a first person hand using a beam emitter but I can’t seem to get the subuv sprite sheet I made for my lighting to work on my beam.

Can you be a little more specific like how it does not work exactly? Sprite sheet not loading? Sprite particles do not change frames? Particles do not appear? Emitter script reports an error?
