Join Brian Bradley for an in-depth discussion in this video Gamma and file unit handling, part of Using Vray RT in Production Rendering.
- [Voiceover] Although the handling of both system and file gamma options has in recent years been greatly simplified in 3ds Max. There is still a chance, should we be working with a version of 3ds Max that has been setup in a non-default way, that we could encounter this gamma mismatch warning dialogue as we work with the provided scene files for this course. The dialogue is simply 3ds Max's way of telling those that the gamma setting saved in the scene file we are loading differ from the settings currently at work in the application itself. To make certain that what you see in 3ds Max as you work matches the visual presentation found in these videos, which have all been created using 3ds Max's default gamma settings.
All we need to do is select the "adopt the files gamma setting and LUT settings" option and all should be fine. If we should, by mistake, go ahead and select the wrong option here though, we don't need to panic as switching gamma options inside 3ds Max is a simple and straightforward process. All what you do is, come to the customize menu, select the preferences option, and then, in the gamma and LUT tab of the dialogue, set gamma to be enabled. Make sure the gamma value is set at 2.2, and also ensure that both boxes in the materials and color section are checked.
Another warning dialogue that we could run into is one connected to both our system and display units setup. As a general rule, we typically model all of our scenes to scale using the metric system. Specifically in the case of this course, centimeters given the small scale of the objects with which we will be working. If you then have 3ds Max setup to use its unit defaults, you will run into this particular error warning. Thankfully, the fix is simple, as all what you do is choose to "adopt the files unit scale." Now, unlike the gamma option that we have already looked at, the consequences of making the wrong choice here, can be a bit more significant, as adopting the re-scale objects option, can often times lead to some fairly serious scene scaling anomalies.
To reiterate then, the option we always want to choose while working with the scene files for this course will be 'adopt the files unit scale." Once we have done that of course, we will need to remember that when working on projects of our own, assuming we don't want to work in the metric system, that we will need to open up the "unit settings" dialogue, go into the "system units" setting, and switch that back to using 3ds Max's default of inches. Also setting the display units to whatever option we are most comfortable working with.
If we follow through on these instructions, everything from the exercise files download should work just fine for us.
