Join EJ Hassenfratz for an in-depth discussion in this video Creating Xpresso user data to control rotation, part of Mograph Techniques: Rigging a Robot Arm in CINEMA 4D.
…So with our robot arm IK rig all set up and good to go.…We're now going to add simple slider controls to be able…to animate our robot claw quickly and easily, using Xpresso.…So to make it easier to animate our claw…without having to dig through, this, long hierarchy to get…to all of our plot elements here, so the…finger is actually at the very bottom of our hierarchy.…As well as the claw rotation,…which I'll just rename this Claw Rotation, so…we know that this is going to control that rotation.…
And this finger, we need to rotate as well.…So, you can see how this finger's symmetry object is…going to come in handy by having the second finger always mirror…the opposite of what the first finger does, so let's create…a new null that we can apply Xpresso to, and we'll…just rename this claw control.…And to add an Xpresso tag, we'll just right click go to cinema…4D tags and all the way down at the bottom, is Xpresso tag.…So Xpresso is a node based system, that has limitless controls…and options that can make your life easier in Cinema 4D.…
