The freehand paint brush disperses 3D geometry in your scene and on any surface with efficient scene management and object orientation control, without the need to select the paint surface or objects.
(Please visit the HELP DOCS for detailed Disperse information).
Think of Disperse as a simple 3D painting 3ds Max plugin where you select the objects you wish to paint, (your brushes), set their combined percentage ratio, and paint. You can transform, add and erase objects by object type as well as exporting to edit mesh.
