Was the problem/file I posted regarding cryptomattes confirmed? I'm having the same issue in the latest release.
If this isn't a bug, perhaps it's just different behavior between Octane 2023 and 2024?

Could we get your scene to check?

Sure can, but it's underwhelming. ;)
Emissive Crypto Error [2024.1].c4d.zip
I can reproduce it with a single primitive and emissive material, but I added a couple other objects for clarity.
If I drag the material between objects... whatever objects it's on ...

Having troubles in the latest Octane C4D Plugin (2024.1.R2) with Cryptomattes not recognizing objects that have materials that contain emissions. If I either render them in an older version of Octane or disconnect the emission node from the Universal Material on the cloner, the cryptos work ...

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.

Derp... forgot to mention.

Mac Pro 2 x 3.46 6-Core Intel Xeon / OSX El Capitan / 128GB RAM / GTX980 / Octane 3.0.3.3 for C4D with R17 (but also tested on Octane 3.0.5.3) / NVIDIA Web Driver 346.03.15f05

I'm rendering some fast spinning tires on a Formula 1 car and I needed to crank the Motion Blur Samples per frame from 1 up to 12. This achieved good results but I was surprised to find that my 300 frame render stopped rendering motion blur after 256 frames (the render finished… the motion blur just ...

Nevermind.
After hunting around on the forum I found 3.02 standalone releases that were not posted in downloads.

Likely because you didn't use an x-particles generator to create any geometry for Octane to render?

Wheres the OSX C4D 3.01 plugin?
This forum page is where the 3.01 plugin points to, but it only provides 3.02.

I need 3.01 because I can't connect to to my networked PC's running 3.01.

What's the last v3 number that works across the network on both platforms with C4D?
