– Houdini 6.5.40 –
1 - create a null object
2 - create a path object
3 - assign/pick the path object to the null object
4 - keyframe the path/position parameter at frame 1, pos = 0
5 “” “” “”“ frame 150 , pos = 1
When I play the animation the null doesn't move smoothly along the path, it just jumps to the end of the path at frame 150. I tried adding a keyframe at frame 75 of pos = .5, but it also just jumps to that pos at that keyframe.
In the channel editor there is no ”curve' generated between the keyframes.
This behavior seems to be a result of whatever interpolation / transform function is built in to the null object.
How do I make the null follow the path ? Or should I just use a geo object ?
Is /was this a bug? I haven't tried it in ver 7 yet.
I was actually trying to get a non-kinematic bone (the pelvis of a character) to follow a path, and observed the “jumping” behavior.
It seems to work ok with a an IK bone, so I guess I can change the pelvis bone to an IK type if that is what will make it work.

null (or no kinematic bone) on a path - no channel curve
