Hello everyone !

I'm using a method similar to this to move and rotate objects (airplanes) along a curve : https://www.youtube.com/watch?v=zYDJURIe_gM [www.youtube.com]

My issue is that while this generally work, the rotation of the object along the tangent doesn't have a continuous acceleration, i.e. the rotation speed can change somewhat abruptly, even with a clean bezier that's perfectly continuous. Is there an easy way to fix this ? My only thought at the moment is to make solver that eases the rotation, but I'm wondering if there's a simpler way. I'm also open to alternative ways to move objects along curves ! (can of surprised there's no built in tool to be honest)

Thanks a lot !

Use the Path Deform SOP instead. Videos like those give Houdini a bad name.

Hey, thanks for the reply ! Isn't the path deform SOP meant to deform the geometry along the curve though ? Here I'm using solid objects (airplanes), so that wouldn't look right.

You can optionally not deform the geometry (using the Rigidity parameter on the Path Deform).

Alternatively, if you pack your geo beforehand (with a Pack SOP), it will not deform.
