Color differences in Frame Buffer vs Saved Image

MorphysMate — Sun, 22 Jul 2018 13:47:45 GMT

Running into a really strange issue that doesn't seem to be gamma related. When I render my scene, the frame buffer is not matching the image that I save. I'm rendering with Vray, using Gamma Correction and saving in 2.2 color space as a png (also tried exr/hdri/jpeg and same results). The saved image is a bit darker, not like it's in 1.0 gamma and what's really strange is the hue is different too.

I'm rendering an orange Corvette and when I sample the color from the Frame Buffer it reads a hue of 7 (which, now that I think about it, is much more red than what is showing in the frame buffer and viewport). When I sample the orange in photoshop it reads a hue of 20. I don't have any color corrections in the VFB. I've tried cloning to Max's Frame Buffer and copying that image to Photoshop and it gives the same results. I even used the snipping tool to copy the Max window and the image is matching in the snipping tool window. But, when I save the snipping tool image and open in PS, it doesn't match and gives the same result. Even the attached snipping tool screen-grab changed when I saved it. I'm starting to think my Windows/Max install is corrupt.

Made some progress. Copy/pasted a screen grab to Photoshop and assigned the icc color profile for my monitors and the colors matched the Frame Buffer.

Is there a way to assign color profiles to render output in Max or do the images always have to be adjusted in post?
