The Material Placement tool is used to select and place materials in your model. This lets you place a material on a face in a component or group (without having to open the component for edit first).
The tool locates the face under the cursor, backs up until it finds where the current material is defined for the face (if it is in the default material), and fixes everything so that the face appear with the proper material - all in one step.
Select the Material Placement tool from the Paintbrush icon on the IRender nXt toolbar. ( )
