The settings on this tab are optional and control how much of the information in the .MTL file is passed through and how much is ignored. If a channel is checked, Grouper will replace the value of that channel with the value in the adjacent swatch for all materials during the conversion process.

The settings on this tab are also used when creating new .MTL files with the tools on the Repair tab.

Click on a swatch to open a standard color dialog. Use the Reset option to restore all the settings on the tab to their normal state. In most cases, you'll want to use these default values.
