Activity Forums Maxon Cinema 4D camera to spline-skips

  • camera to spline-skips

    Posted by Danny Perez-triana on July 10, 2018 at 6:38 pm

    hey everyone, I’m new to c4D and have been trying to animate a camera along a circular spline. I’m able to set the spline as the path, but every time I do a preview, render, the object I’m “shooting” skips and changes position.

    -I Don’t see any key frames for the object or subdivision surface.

    -There are no key frames when it jumps/skips on the timeline.

    any help here would be appreciated,

    hope all is well

    Ignacio

    PS: I’m using C4D version studio R18. I have a video of the preview but can’t upload it to CC as it’s 3mb.

    here is the project file. let me know if you are able to download? the CCow interface is a lil confusing as to how you attach files.

    Hi Ignacio,

    The target object isn’t moving, the camera is flipping its heading at the 90 and 270 positions of the circle spline. If you deactivate your camera so that the default camera is being used, and reframe the scene so that you see the orbiting camera and its spline path from off to the side, you will see its heading flip 180 degrees as it passes the 90 and 270 degree positions of the spline (25% and 75% positions on the path). To correct this, add the same target object into the “Up Vector” slot of the tag’s properties.

    Also, the easiest way to upload files is to simply drag the file into the message window.
