Hello.
My scene wont render and I can't find why.
It rendered correct last night, I modified few stuff here and there and now it won't render at all anymore.
Restarted computer, doesn't help.

I'm OSX 26.2 Apple M1 Ultra 48 core 128 Vram

OctaneRender_Prime_2026.1_for_Cinema4D_v1.8

Here a resumed copy of log :

I redid the scene with last working version… and copy past all new elements 1 by one.
It still crashes time to time but it renders. Maybe A gradient node on Hair Geometry generated mesh ?
Blah !

Hi,

Good to hear you have partially solved.

If you can share the scene with me via Private Message, I can try to have a look to it.

ciao,
Beppe

Ciao Beppe !
I still have many 440 441 errors with any scene in OctaneX, wonder what it is ?

Anyhow I'll share the scene, thank you very much.
