Does no one else have issue of images being saved at a wrong gamma from the picture viewer?

What would be great if you give a better explanation! What's your reference to believe that gamma wrong? What's colorspace in render settings?

In my experience windows photos app is not a good way to test a color profile in a picture, use photoshop or similar sofware, depending of your file type and settings in the render settings the image should be correct in your compositing app.

possibly the photos app is assigning a profile to you picture thats why is looking like that.

check for tonemaped or linear combination of settings in the render settings of c4d.

its the same in Photoshop, any file format. All my old scenes have this issue which were rendered with no problem before.

Simple scene attached.

I think you're talking about saving denoised beauty from render passes, correct?

No no. When the image rendered from the picture viewer its being saved with a wrong gamma. I had to go through the photoshop and invert gamma to .45 to match the image that is shown on the picture viewer.

I am having the same exact issue. Every scene that I render is being saved at a wrong gamma, not what is scene during the render or in the IPR. I did not have this issue before the update, all my scenes rendered beautiful.

OK detected the issue. It's a case when save passes with c4d save formats when you select sRGB colorspace. It still assumes saved images are linear. I'm fixing this part for RC6 builds

Please read my answer one post before. I had to revise a lot of parts in this area(color management).

BUG: Channel Inverter node and Color Correction node.

Channel inverter node does not work for normals.
For example, if I want to invert the green channel of the normal - first I have to split the channels and then use the inverter node on the green channel.
If I use the inverter of the color correction node after separation, it will not work either, only the Invert node works.

Channel Inverter node: X


Invert node: (OK)


Color Correction node: X
