Hi guys,
I need to create a shader that will give a similar effect like the material in the attached pic...
Iv'e tried many many settings but didn't even come close.
Any help or tips are much appreciated

Peace,

Corona Renderer for Cinema 4D - general / Re: Cinema 4D S22
« on: 2020-04-22, 05:50:23 »
S22 doesn't overwrite R21 as you can see from the attached pic (It's S22 but when installed it shows as R22) so you can install it with no fear.
As for corona - I just copied the corona folder from the R21 plugins to the S22 plugins and it works great

MSI actually won't affect materials with reflection/refraction glossiness at 1, so here are some other options:
- Lower the reflection and/or refraction glossiness of your materials which are showing the fireflies to something like 0,99 - this will let MSI kick in
- Use bloom and glare and sharpening and blurring in the VFB post (this may be unwanted if you are planning some post processing in other apps)
- Use highlight clamping (not to be mistaken with highlight compression!) - https://help.c4d.corona-renderer.com/support/solutions/articles/12000035830 (this may be unwanted if you are saving to 32 bits as you will lose high dynamic range)
- Fix it in post by clamping/blurring

Thank you very much - using highlight clamping of 1.5 solved this issue

Thanks for the info...
where can I find the "highlight clamping" ?
Have you checked the link I posted in my last message...?

So sorry, I missed that...
Thanks

Yes, lower values mean less fireflies. But also less realistic illumination, so be careful. Also, the value of 0 is a special case, which wouldn't work for you, so don't set it to zero.
Thanks, I will try this

Hi 3dkobi!

You could try to play with the MSI setting. Look at this article: https://help.c4d.corona-renderer.com/support/solutions/articles/12000035826-what-is-max-sample-intensity-msi-in-corona-renderer-for-cinema-4d-
Thanks for the link, I read the article but didn't understand - Should I lower the MSI ?

Hi guys,
I took an old scene I made 3 years ago in VRay and converted it to Corona in order to make some animations. The exterior shots are great but I'm having some problems in the interior...
I attached the first 3 frames - I'm having "flickering" in some areas with high glossiness - You can see it in the kitchen appliances in the back (which I can solve by simply deactivate those reflections), but the main problem is in the wine glasses. The first test render was set to a level of 5.5% noise and took about 1 hour per frame to render (16cores\32 threads machine), than I lowered the noise to 4% - the render took 2 hours per frame but the results are not much better.
The glass material is simple glass (screenshot attached)
So, is this a normal ?Any solution other than loewr the noise level ? I can't lower the noise threshold anymore - render times will get too high....
And another question - When I rendered a certain test frame to picture viewer it took 1 hour. When I rendered the same frame with same settings with Interactive render it took only 47 minuets to get to the same level noise. Why so much difference between the two ?

Peace,
Kobi

HI, the Corona Select Shader would be very useful here. It will allow you to link up to 99 materials and can be used with keyframe animation. Sorry about the crappy gif
When I try to open your file i get an error message that the plugin "select" is missing.
I'm on c4d r20 & latest corona 4 hotfix 3

Yes, you're right, the green parts are shimmering without B&G...
I don't care so much about the B&G - This is a project for myself to practice things...But I do care about this shimmering in the lights
What can cause them to not render smooth ? maybe it's because I'm rendering with camera MB ?

First - I attach the animation as 2 separate layers.

I tried a few things but nothing helps:
1. I changed the threshold of the bloom&glare (higher\lower)
2. I changed the intensity of the green illumination.
3. I changed from high quality filtering to tent. Tried it with width px of 2, and 1.
Nothing helps...

I can't upload the CXR files since they are huge

Yes, High quality filtering is "on"
