As always, thanks a ton . I’ve tinkered even more various settings, and found a happy middle ground. As far as the nabbing the confidence value and using that in post-processing- is that easily accessible or does it require shader developing and C++ code?

[edit]

Another question I’ve been meaning to ask… Flow and VXGI, sitting in a tree, k-i-s-s-i-n-g. Is there any way to get emissive materials and the like to play with Flow systems, as well as getting a Flow system to contribute to emission? I have some smoke for example, that would be to have lit from emissives or area lights. On that same note, I have some fire that would be (more) amazing if it were contributing light to the scene.

I’m thinking I could “hack” something together, using lighting channels, but am very curious if there is any other solutions possible, or if sort of things is on the roadmap (hint hint, nudge nudge).

Thanks again!

After your question, I discovered that the Confidence texture is not exposed to the post-processing materials, unlike the others (VxgiDiffuse etc.). So now that’s fixed, and you can access that by using a SceneTexture node / VxgiConfidence.

Regarding Flow: it would certainly be nice if smoke and fire could interact with VXGI, but currently they can’t. Not sure about making smoke illuminated by VXGI emitters, that can probably be done with custom tracing shaders; but making fire emit indirect light requires adding a into VXGI to inject light from another voxel volume, used by Flow. That’s currently not implemented.
