That works. I'm not familiar with those 3 buttons, what do they do? It doesn't seem to affect the output render.

Sometimes the 3 buttons appear and sometimes they don't. Is there a way to keep them on permanently?

Thanks!

They appear if necessary, based on your settings.
For example, if you enable AI Denoiser, a DeMain box appears to be able to check the render with or without denoiser.
If you enable Adaptive Sampling, a Noise box appears, to be able to check the green processed pixels by adaptive sampling.
If you enable a pass, in render settings/multi pass tab, a box appears foe each enables pass, like with Render Layer passes.

In 2020.2 CUDA, and future 2021 Mac it is possible to create your own output box, based on a desired layer/passes/AOVs combination, very useful with Render Layer technique, to be able to mix and compose reflections, shadows and backgroud directly in Live View:

Thanks Beppe. Looks like I've got some reading-up to do.

Can I ask another slightly off-topic, but still relevant question? Is it possible to get a 'GI-catcher' as well as shadow catcher?

This is a set up using a floor with a plain white floor (and white background):

This is a version using the shadow-catcher setting in common:

As you can see, there is some nice GI blue on the floor of the first one. Is it possible to retain that using a shadow-catcher?:

Hi,
Shadow Catcher has several limitations, especially with emitters, works well only with Environment.
This is why we have the Render Layer technique.

About GI-Catcher, no sorry, it is not available in Octane SDK.

Hi! All i'm getting is EITHER shadows or the cutout spheres/cubes. I want both combined??

Hi,
you need to go to AOV groups tab in Render Settings, and start by choosing the Render Layer AOV preset, then you can click on the Node Editor button to personalize your setup, adding a color for background, for example:

In Live View you can click on the Out1 box to preview the composition.

ciao,
