Hi, my render output is different from the Corona VFB. I saved it as a PNG, and in the gamma option, I checked override as 2,2. Also, I saved with automatic gamma, but the result is also the same. There is no difference between automatic and override output. How can I save my render as in the viewport? It's urgent, please. Thanks

Sorry, but we cannot provide you with support for such an old version of Corona. Very likely, the issue is already fixed in the newest version. Please download it and check if you are still getting any differences: https://my.chaos.com/download/build?product=Corona

Hi, I update my corona to 13 and 3dsmax to 2026 but the isssue is still going on. I tried everything. First screenshot you see save as png, automatic and 2.2 overrride gamma, but still is not looking like the interactive render. I tried save 16bit tiff open in photoshop and save it, also it didint solve my problem. I open my render with 3dsmax file view image file, in 3dsmax its file, same as interactive render but outside of the 3dsmax, my renders washed out. This is a huge proplem for me. I am working according to the scene, arranging materials, models, maps all for the scene and the outcome has completely different colors.

Probs got to do with colour profiles of your monitor. Open your image in photoshop and assign your monitor colour profile to the image and convert to srgb.

We had some similar cases in the past. This comes from the fact that 3ds Max+Corona is not "color profile-aware". The most straightforward solution is switching your monitor to sRGB in its OSD settings.

/rant mode

Which is the worst of all possible suggestions - sorry for that.

What every unexperienced user (unexperienced in terms of color management) gets wrong is that OCIO is dubbed color management in Max while in reality, it's a rendering space + tone mapping, which has *nothing to do with managing colors as in 'make sure the colors look the same across all my apps*. This is partly due to user ignorance, hidden settings in Windows, partly due to 3ds max who don't care about PS and print, and finally Corona devs who just can't be bothered to finally implement a final ICC-based transform in the VFB and embedding that ICC profile (chosen by the user) when saving files, even after all the posts asking why colors don't look the same in PS/Windows.

Let's see how long until the next user is asking the very same thing, only to be told that sRGB is the way to go (which it isn't, it's just an additional display of ignoring the fact that Corona could and *should* solve it right in the VFB/file).

/rant mode off

And if you want to see this finally solved (or at least mitigated by ensuring color fidelity using a 30+ years old standard by the name of ICC profiles), vote for it:
