Use this dialog to change the appearance of the selected button. You can substitute a different icon for the button, or change to a text button instead. You can also customize the tooltip.
To make a custom icons, you need a series of four files, each beginning with the same prefix which designates the icon group. You can create these images in any paint program.
To use a file with multiple icons, arrange the icons in series, one after the other. For example, if you want three icons to appear, the file that ends in _24i.bmp would be 72 pixels wide and 24 pixels high, and contain the three icons arranged in a row with no space between them.
After you create the icon files, copy them to the UI/icons folder and restart 3ds Max. This lets 3ds Max find and display the group when you access the Edit Button Appearance dialog.
Certain icon sets, including Internal, Classic, Main toolbar, and others, are designed in pairs. In each pair, one icon depicts the button when enabled, and the other shows how it looks when disabled. When Odd Only is on, the interface displays only the odd-numbered icons (enabled), when Odd Only is off, all of the icons, enabled and disabled, are displayed.
