TFD with SSS materials

[zackyd]

I have a SSS marble material that looks great when TFD is disabled but as soon as the smoke is brought into the scene it is turning the material bright white. It appears that the smoke volume is illuminating the Scattering medium material even though there is emission channel in the TFD smoke. I understand that the smoke is reflecting light but this is happening even when I turn off the scattering color in the smoke to black.

Thoughts?

Thanks!

Can you export one frame to an ORBX scene?

I exported it to ORBX and viewed it in Octane and looks like it is rendering correctly there.

Yes! Do you use same versions for SA and plugin? We don't expect different results for same numbers.

well here is a twist. Just updated both the Plugin and Standalone to 3.04.3 and now both are showing up as glowing white like the picture I posted.
Standalone was 3.03.2 before updating to 3.04.3.
Rolling back my C4D plugin to 3.03.2 does render correctly.

It seems correct to me with 3.04.3 standalone. Can't dive to deep to this issue. I have to finish a feature which is long standing.

If you could please re-download the link, I editing the link a few minutes after I posted the link. The normals on the statue are reversed on that one, which is showing up in your photo.
I think I am fine for now with 3.03.2 but it would be great if you could confirm what I am seeing.

Hi zackyd,
I have shared your scene with the devs and they already found and fixed the issue, it will be included in the next SDK release.
What actually happened is the specular material's absorption was ignored where the volume overlapped with it.
Thanks for letting us know.
All the best,
ciao beppe
