- [Instructor] The Data Channel Modifier…has many options for manipulating object information…such as scale.…Today we'll look at the decay operator…which lets us process animation data…to insert time-based effects…in the Data Channel stack.…In a previous movie, I showed how to drive the scale…of elements with the position of a helper object.…And I'll play the animation in this scene…to show you that the size of the cubes is driven…by the position of the helper object.…
A decay operator will let us manipulate that scale data…over time to create a sort of motion trail effect…where the cubes stay scaled up…after the helper has moved away.…I'll stop that and position it on a frame…where we can actually see the cubes.…And select them.…Go over to the Modify panel…and you'll see that I have a Data Channel modifier in place.…And we've got a Node Influence…and Transform Elements operators…both in Sub Object Mode Vertex…and that is required for the decay operator.…
It only works on vertices, not edges, faces or elements.…And even though the vertex selection in the Node Influence…
