Houdini CHOPs Tutorial | Driving SOP Motion and Trails with Channel VOP

Learn how to use CHOPs (Channel Operators) in Houdini to drive object motion and build animated trails in SOPs. We start with a simple sphere in a Geometry node, create a CHOP network with a Channel VOP and Snippet VEX to generate tx and ty channels, and reference those channels to move the sphere in a circular path. Then we move the transforms into SOPs, use Trail to generate a long motion path, add Color at the primitive level, and use an Attribute Wrangle with primitive indices to create a fading alpha along the trail. Finally, we compare the result to a rendered and glow‑processed version done via ROPs and Nuke.
