Overly Dark Render Problem in 3DS Max 2009

I was recently having problems with all renders done in 3D Studio Max 2009—all scenes came out too dark despite the fact that they looked fine in the render window. At first I assumed it was a problem with color profiles and Windows Color Management; after making numerous changes to the color management, the problem persisted.

After browsing the Internet, I found no solutions. Finally, I called Autodesk tech support. At first they too could not give me an answer. After a day they sent an email stating that I should make sure that the ambient light setting was set correctly. But I have been doing 3D for ten years, and the ambient light was set to my needs. I replied that this was not my solution—and since the render always looked fine in the preview window but then were dark in the final output file, I knew something else was wrong.

Finally tech support came back with a solution. I had to turn off the option for “Enable Gamma Correction”. It was an option I had never consciously seen or changed; perhaps I changed it while randomly playing with settings or one of my children made the change. I suspect it may have changed when I installed the 3D Studio 2009 Creativity Extension a few months ago, since it seems to coincide with the time that my dark render problem appeared.

If you are having this same problem, simply click Customize > Preferences > Gamma and LUT and then make sure that the checkbox for “Enable Gamma/LUT Correction” is unchecked. Hopefully that will solve your problem like it solved mine.

Note that this will make the preview render match the output file brightness. You will probably have to add more lights to your scene or increase existing light intensity to make your preview/output brightness match the brightness of the previous "gamma corrected" previews.
