Well, It was pretty stupid, but I just forgot to put a compositing tag on the cylinder and UnTick the "Cast Shadows"

Hi,
I'm trying to exclude a big cylinder with a city texture from a corona sun, but it doesn't seems to work, please see attached images
I'm still on corona 10. C4D R2024

Never mind, I found the problem

Hi Kobi,

I've just checked your scene, disabling the adaptive light solver as requested by my colleague Maru, should resolve this as it does when testing it here. We hope that helps. :)


Thanks, that solved it.
I also found out that where I had problems with the artifacts - If I changed the material from physical material to legacy material that also solve the problem.
Any idea why this happens ?

Can you please check the performance tab for the Adaptive Light Solver?



I'll try that tomorrow morning

Thanks, I was just making sure. In that case, it may be related to the adaptive light solver or adaptive environment sampler.
You can find both options in the development/experimental stuff tab - https://support.chaos.com/hc/en-us/articles/4528469959953
You can try disabling one of them or both and check if the issue persists.

We are interested in the scene itself. Could you please attach it to a support ticket here? https://support.chaos.com/hc/en-us/requests/new

I just opened a ticket with the scene file attached, ticket number is #88434

I'm not sure what options are you referring to, I don't see those options in the development tab.
Regarding sending you the scene - no problem - i'll do it later today

Is this happening when your have UHD Cache set as your secondary GI solver? Or only when using the 4K Cache GI solver?
I tried different GI Solvers, nothing is perfect and those strange squares still appears no matter which solver I use, but It seems that using UHD Cache with preset set to animation instead of still frame gives the best results (much fewer artifact than other methods)

Hi there, is this during rendering or are they in the final images? Also, what does your lighting setup consist of?
This is happening every time I'm rendering in viewport or final rendering...doesn't matter.
Light setup consist of 1 corona sky with HDRI for GI only and 1 skylight with HDRI for reflections & direct visibility. also some spherical corona lights for the interior

No caustics are used

Scaling of materials is correct - this happens on all kind of materials, not just a specific one

Hi guys,
I'm having strange artifacts in my renders (render sample attached) - I want to say that it looks like a bucket problem but I don't know if corona is rendering behind the scene in buckets like vray...
Anyway, anyone has an idea why this is happening ? I have a dead-line for Thursday and really need a solution fast
Peace,
Kobi

Thanks, I followed Beanzvision advice and it works great

Thanks, I'll try that

Hi,
I have a problem in a very complex scene under NDA so I simplified it for the sake of the question - I have 2 objects in the scene and a camera animation (rotating around those objects).
My problem -  I need to produce a render sequences that has only the visible part of the blue sphere visible in the render, and everything else is Alpha - Including the green part of the torus that is in front of the sphere. Like in the second attachment - only what I highlighted should be visible in the render, everything else should be Alpha
how can I achieve that ?

V7 hotfix 2 will be a release primarily dedicated to R25 support, with an addition of some crash/bug fixes.

Thanks,
Jan
Thanks for the clarification

Hello,

we are actively working on delivering a v8 daily build that would support R25 as soon as possible.
The V7 Hotfix 2 version will follow soon after.

Thanks,
Jan

The V7 won't support R25 ? So why bother with V7 hotfix2 ??

Yes, I've checked all those links already...
I just need to understand why the hair color is solid brown. It's like the corona hair material doesn't use the bitmap inside
