![]() The animation will cycle past the last keyframe you set, offsetting from the last keyframed position. Right click the Translate label again and choose Motion Effects ▸ Cycle. It will overshoot and vibrate when it changes direction.Ĭlose the floating parameter editor window. The sphere will appear to be attached to its original animated position by a spring. This will exaggerate the “springiness” of the effect. In the floating parameter editor for the Spring CHOP node, decrease the Spring constant. Open the Motion Effects submenu and choose Spring. If you right click one of the individual X, Y, or Z text boxes, the context menu will only apply to that component, not all three components. In the parameter editor, right click the Translate parameter. Try to add some sharp turns and direction reversals.įor example, move the sphere, set a keyframe with K, go to frame 24, move the sphere to a new location, set a keyframe, go to frame 48, move the sphere, set a keyframe, go to frame 72, move the sphere, set a keyframe. Use the shelf to create a sphere, and animate it. You can jump to this network to edit node parameters, rearrange or delete nodes, and so on. Turn off the Enable effect checkbox item.Īdding effects to a parameter builds a network of CHOP (channel operator) nodes. Houdini opens a pop-up parameter editor you can use to edit the parameters of the effect. Right-click the timeline and open the Motion Effects submenu.Ī floating parameter editor for the CHOP node will appear. Right-click a parameter and open the Motion Effects submenu.Īdd a Motion Effect to the scoped parameters ![]() You can double-click the motionfx node to go inside and inspect the nodes, or delete the motionfx network to remove all motion effects. When you use Motion Effects, Houdini creates a CHOP network node called motionfx at the Scene level ( /obj/motionfx) to contain the CHOP nodes it creates. You can view the network and edit the CHOP nodes to change the effect. You can apply multiple motion effects to the same parameter, and Houdini will simply merge them into the network. Because the effects are procedural, you can edit, refine, and augment them by editing the CHOP network. Overridden parameters have an orange background in the parameter editor.īehind the scenes, Motion Effects build networks of CHOP (channel operator) nodes that override the values of a parameter. You can also use the Jiggle tool or Lag tool on the Modify tab of the shelf to set up motion effects. * Academy Award is a registered trademark of the Academy of Motion Picture Arts and Sciences.You can access the effects on the Motion Effects submenu on the RMB context menu of parameters in the parameter editor, or of the timeline (for scoped parameters).
