Hey guys, I'm totally new to Houdini (not 3D in general, just this software in particular) and I'm having a hard time setting keyframes and animating a spline. I have a plug-in the follows a spline, and I need to move vertices on the spline for the animation. I know this is probably the most “noobiest” of questions, but I'm stumped. Everything else accepts keyframes fine, is there something I'm missing? Can I link it to another object, like a sphere and animate the sphere, having the point follow accordingly? Thanks in advance.
