Animation created in Autodesk Maya may contain additional data, such as ghost color. When you import layered animation created in Maya, the Color RGB property in MotionBuilder displays the color of the selected layer’s ghost. You can use Color RGB to modify the ghost’s color in MotionBuilder before exporting the layered animation back to Maya.
Note: Animation layer ghosts do not display in MotionBuilder.
