.jpg and VFB difference

[les_johnson]

Hello community,

I’m having a strange issue when saving images as a .jpg compared with what is shown on the VFB. I’ve attached examples of the jpg and screenshot of the VFB. Would anyone have any ideas on the cause? Thanks.

Could it be that Color Management in 3ds max is set to OCIO?
How is configured your VFB in Display Correction?

[les_johnson]

Both settings are on sRGB?

[ChuckRT]

for 3ds Max Color Management I meant this one, in recent versions is automatically set to OCIO

Hi. I just checked and can confirm my settings are showing the same as your screenshot.

Damn I was hoping that it could be that, how about the Gamma when saving the image? is it in 1.0 or 2.2?

I always set the Gamma to Override 2.2 manually on every save.

It’s a pain, but it’s the only way I’ve found to get the right color.​

If the 3ds Max native’s color corrections are set to Gamma Workflow and Gamma 2.2, this should happen automatically (Automatic option). If it still happens, attach a sample scene so we can troubleshoot.

I’m in Gamma Workflow and Gamma 2.2 and the automatic mode has never worked for me.

Thanks for the provided scene. Something was deeply messed up with the color management settings in your particular scene. The issue occurred in Scanline as well.

Found a quick fix, however. Go to the Color Management settings, click “Load System Defaults” and afterward switch back to Gamma Workflow.

It doesn’t work. Still the same problem.

My problem has been resolved by manually adjusting the Gamma override figure to 2.2 recommended by @ChuckRT ​. Thanks! ​

Another way is to merge the scene into a fresh one, where Gamma Workflow is set. This worked for me. Also, a good idea is to check your environment variables.

Hi Aleksandar,
what checks should be made on environment variables?

Ignore. I assumed 3ds Max had an environment variable for setting the default color management, but I can’t find such.

[DCHA34]

I think I’ve isolated the problem.
I suspect it’s in my maxstart.max file.

Would you like to test it?​

I doubt there’s a need for that. I guess there are some default settings saved in that scene that get loaded every time.

Autodesk back in 2014 removed Input/Output gamma from the interface and I remember my students keep getting the exact issue .
If you are opening an old scenes that issue will carry on to your other scenes if you didn’t take care of it and change it .
In Maxscript use the following so you don’t need to adjust the gamma manually every time :
Fileoutgamma=2.2
I haven’t tried it yet with the new color management in Max 2024, but I think it should work fine .

[ChuckRT]

This script can access gamma input/output, I use it all the time to change gamma from normal maps
Its completely free
