Example: Looping a Simulation

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 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.

Grid Channel Smoothing

Grid Smoothing is performed after the cache file is loaded for the current frame, so for large grids it could cause significant lag after changing frames. To prevent this from occurring, switch it off during the design process and re-enable it again before rendering.
