Thank you for all the replies and suggestions.
I removed full denoising and set denoise level to 4 in render settings.
The banding is gone. Final render looks much better.

Yes that’s it!
So it’s called banding.
I’m sorry but I didn’t know that and
that is why was difficult to explain.
So the only way to reduce it is the
3 options you explained?
Thank you very much for the help!

Thank you for the reply.
I am talking about the left part of the image where its empty.
The images I uploaded are different, one is interactive render 25 passes and
the other is VFB render with 35 passes 3% noise.
The VFB render is not so smooth, you can see like gradients
and each one is getting darker as you look up towards top of the image.
Its more noticeable at the top part of the image above where I typed VFB.
As you look upwards as the image darkens.
Im not sure if its supposed to be like this, maybe it is, only it does not look nice.
But in the interactive render the transitions from lighter to darker is so much more
smoother, barley noticeable compared to the VFB.
I created in photoshop a comparison with the 2 right next to each other. Only the left side of the 2 images
and I painted over with a blue brush where each different transition begins.
I don't have bloom and glare enabled and have not touched sample intensity, I don't know where it is in corona or what it does.

[Max] General Discussion / Ugly highlights and shadows after render

« on: 2018-05-11, 09:11:38 »

I have a scene and after I create the render with the corona VFB the highlights and shadows on the background plane look worse then
when I create a render with the interactive render with a max passes of 25.
It looks like there are gradients of different shades of greys and lighter patches.
Im wondering if something has to be adjusted in render settings or maybe
I am doing something wrong or this is the way it should look. I tried to clean it up with photoshop after but still does not look nice.
I look at some tutorials and all suggested not to make adjustments in render settings because the default settings are fine.
The only adjustment I made is noise level limit  to 3, and denoiseing to full, and denoise amount to 1.
I uploaded two files from the 2 renders to show the difference.

[C4D] General Discussion / Insert downloaded materials into scene

« on: 2018-04-15, 13:05:52 »

Hi there,

I downloaded some materials from corona-materials.de and would like to use them in my current scene.
The problem is I don't know how to insert the downloaded material into my scene.
I tried to just drag the material into my scene and also tried opening them from the merge objects menu, but
the material always opens up in a new scene window.
How is it possible to insert the materials into the current scene I'm using?

Yes I tried with turning off cast shadow for the sky in the compositing tag.
But still after I render it in the png the area around the object will be grey color. So when I place it in Photoshop on top of a white layer the white turns to grey.
It’s like a gradient grey that is lighter towards the light but more strong towards the end where the objects are.
I’m starting to think it’s impossible to achieve the effect I want.

Hi there guys,

I would like to ask you abut  something again. I am trying to render a scene where I have 3 objects (cogwheels) with a transparent background and after the render is done I would like to add in photoshop a 100% white background.
I would like that the  final scene has only the 3 cogwheels the  shadows casted by the  3 cogwheels from the 2 corona lights and that the HDRI sky's reflections are visible in the cogwheels; but I dont want the shadows casted by the sky to be shown. (For this reason I added a compositing tag to the sky and disable seen by GI) And I want to have a transparent background.
My problem is that when I make the final render I get the transparency but everything else the objects is a grey color which is visible when after I open up the PNG file in photoshop and create a new layer under it and fill it with white. I uploaded some screenshots of this.
Is there a way to render what I would like to achieve? 3 cogwheels with their shadows casted by the 2 corona lights and HDRI sky reflections visible on the cogwheels but no sky shadows, all this with a transparent background. And no grey colour in the rest of the scene.
I attached all the files, screenshots where the grey color around the objects is visible in PS and the final render file in PNG. I can't upload the  HDRI file I use for the sky because it is to large, but other HDRI would be fine too I suppose.

Thank you!

Oh my god it looks awesome, so beautiful.
Thank you so much! I will try it.
What format did you save it so you can change the background later ?

Hi everyone!

I am new to cinema 4D and Corona. I have a pretty basic scene and would like the final render to have a transparent background so the plane is not visible but the shadows casted onto the plane are still there. I would like to replace the original background in photoshop after the render is done. From what I found online is that I have to do multi pass rendering. Can someone please explain to me how to do this and set it up.
I attached the C4D file as well if it helps.
Thank you.
