Controlling Alembic playback
You can customize importing and playing back Alembic data through the properties on the Alembic Stream Player component.
When you change the Time parameter you can see the Alembic objects moving. To play the animation, you can control the Time parameter from the Timeline window, Animation window, or via scripts.
Vertex Motion Scale is a magnification factor when calculating velocity. The greater the velocity and motion scale, the more blurring the Motion Blur post-processing effect applies.
