Gamma and units setup

- [Instructor] If you were working with your copy of 3ds Max set up in a non-default way, then it is quite possible that you will encounter this gamma mismatch warning dialog as you open up any Max files provided with this course. The dialog is actually 3ds Max's way of telling us that the gamma settings saved inside the file are different than those currently at work inside the application. So make certain that what you see in 3ds Max as you work with these scenes matches the visual presentation found in the videos here which have been created using 3ds Max's default gamma options, all you need do each time you encounter the dialog is choose the adopt the files gamma and LUT settings options and all should be fine. If you accidentally make the wrong choice, no need to panic as stitching the gamma options inside Max is a straightforward process. All we need do is come to the Customize menu, select the Preferences option and then in the Gamma and LUT tab of the dialog, set gamma to be enabled, make sure the gamma value is set at 2.2 and then ensure that both boxes in the materials and color section are checked as well. Another warning that we could run into is one connected to our system and display unit setup. As a general rule, we typically model our scenes to scale using the metric system, specifically in the case of this course, centimeters. If you have 3ds Max set to use its unit defaults then, you will run into this error as you open the provided scene files. The fix again is simple in that all we need do is choose the adopt the files unit scale option. Now unlike gamma, the consequences of making the wrong choice here can be a bit more significant given that choosing the rescale objects option can often times lead to some fairly serious scene anomalies.
