Hi people
I´m testing corona with a vray scene, and i get this problem with the output file. It´s black.
Also the coronacammod does not change the image, simply does not work.
The setting overall is desabled(untick).
Also tried to save with gamma1.0 and it´s the same issue.
I did the material convertion and the ligt also, evn made corona sun to see if the problem was with th converted sun.
Can anyone help?

-which version of 3ds max are you using?
-which version of Corona?
-in 3ds max, go to rendering>gamma lut setup, how does the window look?
-when you are saving, what gamma options do you choose?
Is the saved file BLACK like you said or DARK, like in the posted picture?
Hello
-gamma settings is “automatic” i do not imput any value
don´t know what is wrong
after a few ries i changed the output gamma to 2.2 with a script , so now it´s imput 2.2 and output 2.2 . and the images comes out correct.
In vray i allways use output 1.0 why is in corona diferente?
I have this problem too. why this happen?
I found the reason,
We need to save it in open exr (or any other high dynamic range) format , if we don’t MAX will make gama multiplied by .44(1/2.2)
Hi,
You can override output gamma in Save picture dialog, or you can correct output gamma in file CurrentDefaults.ini to keep this output gamma as default. It’s located C:\Users\xxxx\AppData\Local\Autodesk\3dsMax\2014 - 64bit\ENU\en-US\defaults\MAX.vray (or Max / Max.mental ray if you use those defaults)
This way you can save whatever format with correct gamma
Hi, several methods of changing gamma in different versions of 3ds Max are listed in this article:
