- [Instructor] Now that we have seen how to build some simple procedural animation channels in a chop network, the next important piece of the puzzle is to see how then we can connect the output of those channels to a transform node to actually take over the rotation of this geometry. And we're going to do that with a very simple expression within the parameter field of our transform node. So I'm going to go into the model here. And what I'm going to do, we've got this transform node here that had our manual animation on it. I'm going to leave that there, but I'm just going to bypass it for now. And then underneath that transform node, I'm just going to make another one. So I'm going to right click, type transform, and there we go, and then it pushes everything down. So what we want to do here is instead of setting these key frames, we want to say, okay for X, go inside this rotCHOP, this rotation chop network we made, go find the RX channel and just have this data be fed by that…
