I might be missing something, but I can not get the lighting (real-time) view to work. I have tried installing standalone to match. I have 2 A5000's, but one 1 A5000 card active in both c4D and standalone. I'm using Windows, and C4D 2026.4. I hit the lighting button and it is black. I have tried ...

Can you confirm that the new NRC only works with a single GPU? With multiple GPUs (a5000's) I have a visible seam running down the middle in both live preview and render.

**Update - it looks like it might be an issue with static noise on? If I disable static noise, , NRC seems to be working at ...

Just updated both C4D 2025 and Octane to the latest. From my few minutes of testing, it appears much more stable now, and I am not experiencing the lag issues and crashes with material and opengl previews turned on. Well done and thanks for the quick fix!

I'm getting a lot of crashes doing simple tasks (like dropping a material onto an object, or changing IOR). I believe I have isolated it to having cards with RTX mixed with non-RTX cards and having RTX acceleration turned on. These crashes are new with either C4D 2025 or the 2024.1 release, as I ...

Have you tried making it a mirror and putting either a light or a lit white surface behind it?

Hi Ahmet,

Is there any way you can enable the pins for Albedo and Normal on the Open Image Denoiser. There is currently no way to assign those. Thanks!

Thanks for making this so quickly! It looks like the PostFX Media AOV is missing from Render AOVs.

Hi Ahmet,

Thank you for this! A few questions:

1. Looks like there is a limit of 4 Analytic Lights with light beams, is this correct? I know there is a limit to 8 analytic lights for now.

2. It appears that primitive lights are facing the wrong direction on the z axis when using area shape of ...
