Bitmaps have a Time rollout with controls that let you synchronize an animated bitmap with scene animation.
Start Frame: The frame number of the 3DStudio MAX scene at which the bitmap animation begins to play.
Playback Rate: Sets the bitmap’s playback rate. This value is a multiplier: 1.0 is one bitmap frame per scene frame, 2.0 is twice as fast, 3.33 is 1/3 as fast, and so on. Default = 1.0.
End Condition: Sets what happens when the bitmap animation ends (if the bitmap animation happens to be shorter than the scene).
Loop causes the bitmap animation to begin over again.
Ping Pong plays the bitmap animation again, but backwards.
Hold freezes on the last frame of the bitmap animation.
