Cinema4D version 2020.2.4-R2 (Obsolete stable) 20.06.2021

Hi, Aoktar!
Overall this plugin version is really stable.
One question: I have this interior scene in which I work with exterior light and interior spot lights: they are inside a cloner. INe of the spot cleans light very well while another struggles a lot to clean. Why does that happen? - Please refer to picture.
Regards,

Are you using primitives option with AI lighting? It should help a lot. Thanks for feedback!

I am using primitives and AI light whenever I can.
I am able to use .ies files into shader's emitter slot. I cannot reproduce the same effect with light emitter on primitives - an .IES file in distribution slot for a primitive square light - if there is something I am missing please tell me.
What I don't understand mainly is why, 1 out of 3 instances, there is a different noise pattern.

Update: It turns out noise pattern is coming from exterior light, in which case is a planar light (rectangle) with primitive turned ON.
I attach two pictures: the noise pattern appears when AI is ON. AI off eliminates this pattern.
Not the first time I see this issue (first time I saw was one or two versions ago 2018 or maybe v4).

I attach another example where AI light makes it harder to clean.
I know these are exceptions, AI light works mostly great!

Probably not new in this build, but i had my renders ruined with a VDB that has volume emission enabled.
When a mesh with a medium intersects the voxels, i get very strange artifacts. Octane really is super glitchy and slow with volumes.. Either the volumes intersect themselves, or they cause artifacts with transparent textures on medium-high step lengths.

Is there a way to avoid these? Doesnt matter if the mesh has absorption, scattering or randomwalk medium. Step length does not have an effect on it (lower length, no improvements)

Octane really is super glitchy and slow with volumes..

Yes and i dont know if its this version or r23 that i migrated or both, but it lags a lot with TFD. Viewport/LV lag.
I think volumes need a lot of improvement in core, they feel very heavy in both render times/viewport

Hi guys,
did you see the new features in 2021.1 SDK?
viewtopic.php?f=33&t=77764

Both AI Light and Volume rendering are under revision.

Here is the link to the first c4doctane version based on the new SDK (not ready for production):
viewtopic.php?f=85&t=77937

And some details on the new Volume rendering system:

Hey Beppe,

Thanks for the link. Yes i am aware of development, but this just for overlapping, its not about volume performance which is poor at the moment. And while im used to slow rendering, I am not used in lagging this heavy in lv with a single frame in tfd with a few mil voxels.

Let me know if you have similar issues or i can share a scene.

Thanks

Thanks, Beppe. I didn't remember it: good to know.

Yes please, share a scene with me that shows the issue.
