This compound modifies particle velocity over its lifetime using a profile curve. This lets you easily make the particles accelerate or decelerate. It uses the point cloud's Age attribute as a reference.
Plug this compound's Execute output into an Execute on Emit port of the Emit compound, or any Execute port of other compounds such as Slide on Surface, Bounce on Surface, or Stick to Surface. You can also plug its Execute output into a Port on the ICETree node.
