change color and light

[o.peiro]

Hi
From time to time, the files that I save and close and I want to continue working again the next day, the color and light of the image looks like this (in this rendering, only 1 material has changed compared to the previous rendering)

That looks like some sort of tone mapping issue. Best bet is to send in the scene via private uploader so we can see what overrides (from camera, scene, etc.) are being used, links in my signature. Also, which version of Max, which version of Corona. Thanks!

PS - also, which version of Max, which version of Corona. Thanks!

Did you by any chance change the "highlight clamping" value in Render Setup > System? It looks exactly like the effect of using highlight clamping. By default it is set to 0.

No, I did not change this parameter manually.

If you are able to reproduce it, our uploader accepts files up to 10 gigabytes. :)
