KMCOBJ files are three dimensional object files that can be imported into a Kinemac animation. The KMCOBJ file may be dragged onto the 'Stage' window after opening or creating a .KMC file. The KMCOBJ file may contain references to other images or video clips that have been applied to the sprite. By default, the KMCOBJ files are not saved along with their referenced file. A sprite may be saved with its associated image and movie textures by holding down the Option key and dragging the KMCOBJ file to the Finder.
