Just tried out the new version on one of my old scenes and I can't get denoising to work with Photon Tracing. It just seems to cycle endlessly. Is this a known issue?

It would be extremely helpful if a scatter node would support a velocity vector.
(so when writing out a scatter matrix that you can give a vector for each instance (maybe even with a rotation vector)).

Could this please be implemented?

I found two serious shading issues !

One is caused by strong light or HDR on the Diffuse channel :

Another is caused by Transmission channel using GGX energy preserve mode :

I tested different light conditions, materials and always the same issue. Of course there isn't any gloss or reflection effects.

Transmission issue is caused by coating layer on transmission channel ( diffuse ones ) in GGX energy preserve mode :

EDIT : All of these issues are caused by strong point light halo like sun or HDRi map :

Also thank you for updated Octane Sky Model ! It looks even better than Hosek&Wilkie because can be more customized.

Can you export those scenes to ORBX and PM me please?

While it's nice to have videos, providing an ORBX is the best way for us to reproduce the issue.

Another possible issue. HDRI maps cause many fireflies on reflections if they are set to visible environment but if they are set to primary there is no fireflies.

This may be caused by wrong default GI clamp value in Cinema 4D plugin. GI clamp = 1 works fine here without any underlighting issue and fireflies. Before GI clamp at 1 was the same as no GI at all.

This may be something you already know about this build... but Volumetric Spotlights do not render correctly if the camera passes inside the Light's cone. The volumetrics disappear completely while inside the cone... reappear when you exit. Renders correctly on PC.
