Opens the Windows-standard Media Player to play the current preview animation.
When you use Create Preview Animation, by default 3ds Max stores the output preview in a file called _scene.avi. Play Preview Animation this file into Media Player. If you want to keep the preview file, use Save Preview Animation As to save the preview under another file name; otherwise, the next Create Preview Animation will overwrite _scene.avi.
The Media Player has its own Help system.
