Below is a simple FumeFX smoke plume scene.

Usually beauty pass is maked in rendering software, but why not speed entire shading workflow by moving it to compositing process? It’s pretty much typical standart in many studios nowadays, let’s take a look how to make that.

Here is the same fluid grid with different lights by areas. Every color represent another fill angle. In our situation green color is key light, red – fill light, blue – back light.

What is cool, that in compositing every color can be separated as another pass. Three passes from just one rendering.

    Great tips, thank you very much. Do you know how is it possible with fumefx and vray to have a GI pass for compositing ? vrayGloblIllumination, rawlighting, totalighting, etc seem not to work.

      Thank you. Never tried and never ever needed that. Maybe it’s better have separate lighting pass prepared for compositing need.

    hey! In Fusion you can use this RGB as XYZ normals and then adjust the light throught the Shader node!

      Michail, thank you for the tip. When you have rendered rgb pass, there is even more advanced ways to use it (fake position pass and use real lights in 3d space), but I hope everyone will choose method by own compositing experience.
      I tried your tip, didn’t know this one, thank you!
