Batch render multiple scenes with render layers and different settings?

Support Lighting and Rendering

Hello all!

Too many times, I thought about it, and don’t know that’s possible or not.

For example, I have Blend with multiple scenes, each scene have a Render Layer with objects, with GI shadows, and with clear BG. Last two layers are pre-composed to Shadow Pass and saved via File Output node. Each layer took too many time for render, but it can be reduced, because shadow layers don’t require the same settings of sampling, etc, like layer with objects. Now I render one layer, then I change settings and render last two layers, manually. But it’s not handy, and high chance for a mistake.

Does anybody knows, is there any options to automate such kind of operation? Or my scenario of usage is wrong in the root?

Moved from “General Forums > Blender and CG Discussions” to “Support > Lighting and Rendering” (could also fit in Compositing and Post Processing)

If you’re truly rendering with separate scenes (as opposed to multiple render layers in the same scene) and compositing afterwards, you should be able to set scene-specific render settings.
