You can have 3ds Max correct illegal colors automatically when you render, depending on the settings in the Rendering tab on page 7768 of the Customize/Preferences dialog on page 7743. Use this option as a guide only. The colors in a rendered scene depend not only on the material color but also on the intensity and color of the lighting. A material that shows as safe in the sample slot might become illegal if rendered under several bright lights. A safe practice for video is to use colors whose saturation is less than 80 to 85 percent. Procedures To check for illegal video colors: 1 On the Material Editor, turn on Video Color Check on page 5332. The active sample slot now renders "illegal" pixels as black. Illegal pixels have a color that is beyond the safe video threshold. If Video Color Check detects illegal colors, try reducing the saturation of the material colors in question. 2 You can also check for legal video colors when you render a scene. To change the video system: NTSC on page 8059 is the default video system to check. You can change the video checking to PAL on page 8078. ■ In the Tools menu > Options > Options dialog > Rendering panel on page 7768 > Video Color Check group, change the setting to PAL. The sample slot does not automatically update when you change the video system preference. Turn video checking off and back on to see the change. NOTE The Rendering panel also shows options for choosing alternate ways to display illegal pixels. These apply to renderings only, not to the sample slots in the Material Editor.
