The following example demonstrates how the Cache Origin and Play Speed can be used to offset and speed up the input cache files.

The files go from simulationFrame_000 to simulationFrame_030. When the Timeline Origin is set to 100, they are read as if they were saved as simulationFrame_100 to simulationFrame_130.

The Cache Origin is then used to specify which simulationFrame will be placed on Timeline Origin = 100. Because Cache Origin is set to 10, the whole sequence is shifted 10 frames back such that simulationFrame_000 is placed at frame 90. Thus, the sequence now goes from frame 90 to frame 120.

The Play Speed is then set to 2.0. Those thirty frames are now reduced to fifteen. The Cache Origin frame is treated as the middle point when shrinking the sequence.

The following example demonstrates how the Input roll-out parameters can be used to loop a simulation.

The Timeline Origin parameter is set to 0 - this will be the first frame of the timeline which the Input Path files read into the scene by the Simulator where the selected simulated cache files will be placed on.

The Cache Origin is set to 10 so simulationFrame_010 will be read and placed at Timeline Origin = 0.

The Play Length is set to 15 so the sequence now repeats itself every 15 frames when played back (those are actually simulationFrame_010 to simulationFrame_025).

Finally, the Loop Overlap parameter is set to 5 to provide a few extra frames for blending the start and end of the loop together in a smooth transition.
