Hi guys!
I've updated c4d to 2025 few days ago and installed the Corona 13 daily that supports it.
Renders in the vfb and interactive (both viewport and window) are working fine. Unluckily if I render the viewport colours are different, looks like the gamma is wrong.
I think this could be a color space problem, but I checked the linear space and everything should be ok

Hi there Teo,
Thank you for contacting us.
Could you please elaborate a little bit more about the issue?
As far as I understand, the rendered image (regular render) using the VFB looks ok; the rendered image using the IR (Interactive Rendering) in the VFB also looks ok, but the IR for the Viewport is the one that is not working as expected, am I correct?
Could you please double-check if the Linear Workflow is disabled for the Viewport?
Looking forward to hearing from you.
Have a nice day/evening.
Kind regards.

Hi there! Yes you did understand perfectly what the problem is.
These attached are my current settings for colour space. I didn't touch anything since I installed c4d 2025 few days ago.
Turning on and off the linear option in the viewport doesn't change the colours behaviour
-
Hello Teo,
Thank you so much for your reply.
What I meant is enabling/disabling the LW for the viewport. (see attached image)
Does it make any difference by enabling it?
I tried reproducing the issue, but the only way to reproduce it was by disabling the LW for the Viewport; this way, I got a similar result as yours.
Looking forward to hearing from you soon.
Have an amazing day/evening.

Hey Benjamin,
so I tried turning this on and off and the result is always the same (wrong).
See attached screenshots please

Hello Teo,
Thank you for your reply.
Would you be so kind as to share with me your scene project? (Or at least a stripped-down version where the issue is reproducible)
If you don't feel comfortable sharing a project here, you can submit a support ticket, and we can continue from there.
Note: Please do not forget to include any necessary assets required with your scene project.
Looking forward to hearing from you.
Kind regards.

Hi Benjamin,
since the problem occurs in every scene I'm just sharing with you a random one.

Thank you

I have had a similar issue, but it was always the Interactive Viewport. I opened your scene and viewport render, interactive viewport, picture viewer and VFB all matched.
The Linear Workflow Shading was ON for me. When I turned it off, then the issue showed up. Interestingly, previously for me. it was always an older project file. If I copied everything, created a blank scene and then pasted, this problem went away.
Maybe the Linear setting was a default at some point.

Don't use the Legacy (sRGB linear workflow) Color Space. Try the scene-linear Rec2020 Color Space in the Project Color Management drop down. I had a Standard Render (yes I still use that from time to time) issue. The Render Viewport colors were very dark compared to the Render to Picture Viewer output. I also tried opening the file in C4d 2023 and had no color problems.

Tried to change color space but it doesn't fix the issue.
This problem is indeed some setting in my c4d version

Hello @TeoRossi93,
Did you manage to adjust the color management settings?
As someone else already mentioned, the issue is caused by the color management feature in Cinema 4D.
Using different color settings will return different results.
You can also continue using the default color settings for the Cinema 4D 2025 version, which is "ACEScg".
Note: If you change the color management settings, please always make sure the "convert colors" checkbox is enabled.
Please let me know the outcome.
Looking forward to hearing from you soon.

May be...
From Maxon's C4D v 2025.0.2 Release Notes:
Color Management - Fixed an issue with the Render Color Space token when the Render Space is set to ACEScg
- Fixed an issue with saving Multi-Pass images in the wrong color space[/l][/l]
