Combining eevee and cycles pass into screen space reflection

Support Compositing and Post Processing
1

So I am using eevee + cycles because I want emission material of particles to be driven by velocity of particles. I Render the whole scene in eevee, then I have cycles pass on second scene that renders only emission material on particles. Then in compositing I just mix the cycles pass into eevee with lighten.

I guess there are 2 questions:

  1. Is there a way to drive emission per particle in eevee (I heard animation nodes might be able to do this? Also I guess one day the particle info node will work in eevee as well)

  2. Is there a way how to input composited texture into eevee screen space reflection? (My guess is probably not)

For the first one… kind of. They won’t have shadows, though. (Just use a lamp as the object instance for the particles)

As for the second one… nope! Not as far as I know!
