Different Colors Between Corona VFB and Saved Image

(1/1)

eduardofenabel:
Hello,
Hope you guys are doing all right.

I'm using Max 2025 and Corona 12. In the Corona VFB, the render looks fine, but when I save it, the colors appear very different.
I tried changing the "OCIO - 3ds Max Default" to "Gamma Workflow 2.2" and while the saved render changes, it still remains different from what I see in the Corona VFB.

Can someone please help?
Thank you,
Eduardo

I believe default windows 10/11 photoviewer app is not colour-managed and will display incorrectly.

What is the comparison when you open in Photoshop?

Right, Win10/11 photo viewer discard *any* embedded color profile (which is not present anyway in an image saved from Max) and applies some arbitrary contrast/levels operations to make images pop out.

If you upgraded from Win7 you probably have the old Win7 image viewer, use that one instead, or any other image viewer that shows original pixel values without any arbitrary enhancements.

@eduardofenabel are you using Corona 12 or Corona 12 Hotfix 1? There were multiple fixes in Hotfix 1, which could affect your results - https://www.chaos.com/corona/download
Other than that, to what format are you saving your images and what settings do you use in the 3ds Max save dialog?
