I have a character model that I’d like to render in Cycles only and the rest of the scene in Eevee.

This was suggested to me by someone I had contacted sometime ago. He said to speed up render times, they’d render their characters in cycles and the rest in Eevee but I cannot remember where I spoke with the guy, otherwise I would ask him how he does it.

I’ve searched the internet but all I’m finding is that it’s not possible to composite Eevee and cycles together.

There must be someway to achieve this!

Does anyone have an ideas how this might be done?

  • $\begingroup$ you can use the Compositor to mix movies made with Eevee and others made with Cycles $\endgroup$

  • $\begingroup$ Most likely the unknown someone said: render the characters in cycles (as EXR image sequence), Then, in the compositor bring the rendered image sequence and composite them together with the scene rendered in eevee... $\endgroup$

    $\begingroup$ It can be done with separate scenes within the blend file. Andrew Price does the trick in order to render with different compute devices in this tutorial: youtu.be/9L8qOq1Shiw?t=3896 $\endgroup$

Name your first scene "Cycles" and organize your outliner like this:
Outliner Cycles

Add a scene and select Linked Copy.
New Scene
I'll name the new scene "Eevee."

Set up the Eevee scene's outliner like this:
Eevee Outliner

In the Eevee scene, set up the materials of the objects in the Cycles collection like so:
Nodes

Be sure to set Blend Mode to Alpha Clip (unless otherwise necessary).
Settings

Back in the Cycles scene, set up the compositing something like this:
Compositing

And be sure to enable transparency in the film settings:
Film Transparency

Whenever you render from the Cycles scene (the one witch includes the Eevee render in its compositing nodes), both scenes will render automatically.
