Material Editor > Type button

Material Editor menu > Material menu > Change Material/Map Type

Click the Type button to display the Material/Map Browser and choose which material type or map type to use.

When changing a material's type, the original material type is replaced unless you choose a compound material, in which case a Replace Material dialog is displayed. The Replace Material dialog lets you choose between discarding the original material or using it as a sub-material within the new material.

For a standalone map (a map at the top level), clicking the Type button lets you change the map type instead of the material type. However, you can't use this button to make a map standalone. To make a standalone map, you have to click Get Material and choose a map from the Browser it displays.

When you change the type of a standalone map, a Replace Map dialog is displayed. The Replace Map dialog lets you choose between discarding the original map or using it as a sub-map within the new map.
