C4D Tutorial: Spline Rail Tip

In this tutorial I’ll show you a quick tip for using the align to spline tag in conjunction with the spline rail. It’s a really important tip if you’re having trouble having an item travel along a path while having the correct rotation.

    Actually you can also try rotating the axis of the jack to mae it follow the spline. This also works most of the time.

    And as for the growing of cabel and movement of the jack – to make tham move and grow with same speed you should change the Intermediate Points in the spline (in your scene Helix) to Uniform or Subdivided. This way you won’t have to check so that the jack and cable stick together all the frames.

    Good luck and thank you.

    Good tut. I found it easier to align a null object to the spline and then add a character constraint tag to the actual object using the tag “Character>constraint”. Select PSR and dragging the null into the target. Now you can “offset” rotation however you see fit.

  4. Hey Joren,
    I recently worked on a project like this and came up with a alternate version of this example using Mospline. Feel free to download and share. In my version I created Mospline and used a Helix as my Reference Spline. Animated the End in Mospline. I also added the plug to a cloner and set it my Object to mospline and offset to 99.8 and used a count of 1. This way it follows my initial Mospline animation so I only used 2 keyframes. This way since its mospline you can use all the effectors to it like Formula so it adds movement to the spline.. Hope you enjoy..
