By the way, older ORBX files are rendering just fine in Stand Alone.

Could you share a scene with us that has this issue?

Am I missing something?
Regards,

They are logging errors, not crashes. Those errors should have no efffect on your scene unless you are using the Upsampler or Radiance cache. We will shortly be releasing a hotfix for these logging errors.

Today I tried the new version of X-Particles and found that I can preview when rendering nxMesher, but it crashes when sending a full render. Turning off nxMesher also causes Octane to crash. I don't know if this issue is related to Octane or INSYDIUM, so I will report it to both places.
Cheers ...

That is great and exciting, thanks to your continous great work! And I love to be able to look at the trello plan!

Both logging errors should not impede you from using the plugin. We have a fix for them that we will release shortly.

Hi all,

Here is our Octane 2026.1 for Cinema4D release
For this build we have improved and expanded Octane 2026 support across the plugin,
and fixed a couple of other issues and added User Data Tag and Mograph Data support!

While Octane 2026 now out of beta, and we implemented the new features ...

We support the motion blur data for x-particles when it exists. Which I believe should always exist when rendering in the PV.
Let me know if this is not the case.

The live viewer might not always show them when scrubbing the timeline.

Hey everyone,

I’m struggling with a color mismatch between OctaneRender and After Effects when working in ACES 1.2. My EXR looks washed out in AE, with dull whites compared to the Octane Live Viewer.

Here are my settings:
