Rendering Pyro Passes Workflow [solved]

[evanrudefx]

Hey,

I am looking for advice on a good workflow for rendering and compositing a pyro sim with both fire and smoke. I know that fire has no density, only smoke. So, I turned on two image planes, one for smoke_mask and one for fire_mask. What exactly do I do once I am inside nuke and what are the intended purposes for the fire and smoke masks? How are they to be used together? 

Thanks,

Evan

 

edit: Do I need to render out fire and smoke separately or is one pass with both fire and smoke mask enough?

Thanks, I think my question was more of how to specifically use fire/smoke mask in nuke and what were they intended for. I see you used other passes then fire/smoke pass.

They (fire/smoke mask) intended for masking Change color, intensity, other operations...
The main goal is independent control in each pass, this can be done by example above.
