evanrudefx Posted October 25, 2017 Share Posted October 25, 2017 (edited) 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?

evanrudefx Posted October 29, 2017 Author Share Posted October 29, 2017 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. Quote Link to comment Share on other sites More sharing options...
fencer Posted October 29, 2017 Share Posted October 29, 2017 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. 1 Quote Link to comment Share on other sites More sharing options...
