I’m a staff member at the University of Michigan 3D Lab and have been working on a project using both Krakatoa and Deadline; and have run into a bit of a problem. When rendering a single image within just Krakatoa I get the image shown on the right hand of the desktop image (this is what I want the entire animation to look like). However, when I send the entire animation to Deadline to render out, each frame looks like the image on the left side of the desktop image. I’ve also noticed that if I open the single image in photo viewer instead of the 3DS Max image viewer I also get the image that is seen on the left.
All pieces of advice are welcome. I’ve also attached the file I’m using if anyone wants to see for themselves to see what is wrong. galaxy.max (1.77 MB)
3ds Max applies a gamma correction of 2.2 by default to the image shown in the Rendered Frame Window (see the title bar in the screenshot, it says “Gamma 2.2”).
When the image is saved though, the Gamma is not applied to it, so the gamma is 1.0 and the image appears darker. The REAL data saved to the image is thus what you see on the left.
Krakatoa calculates full floating point data (totally unclamped), so if you save to something like OpenEXR, you will get all the data needed to do post-processing.
Alternatively, you can save to 48bit PNG to get enough color depth for post.
3ds Max ships with Composite (based on Toxik), or you could use After Effects, Nuke, Fusion, Combustion etc. to apply the Gamma if you WANT the result seen inside of 3ds Max.
To see the REAL uncorrected image in Max to make the two match, go to Customize>Preferences>Gamma and LUT tab, and turn it off.
