    after doing a 4 corner track in combustion. i noticed that my bottm 2 points were off. is there a way to offset the lower lfet and right points without affecting the tracking data. i have done this in ffi plenty of times. i just can’t figure out how to do it in c4. the points don’t have an offset option only x and y positions.

    nesting the layer didn’t work because the pivot doesn’t share the same information of the track and scale. same goes for the null object.

    thanx for the help in advance

    offset the corner points (track, after offset the position of corner points), or use null (to store values) and expressions to make the offset

    Hi,

    Once you turn off the tracker the tracked data will be applied to each of the corner points and you can adjust each corner points X and Y key frames individually in the time line. Just make sure the animate button is off and you can offset them.

    the name of the game is avoid hand tracking 110 frames whew a girl is typing on a t-mobile sidekick as the camera is looking down on them and passing them. i’m cool on hand tracking. i’ll just finish in ffi.

    i just thought combustion will be able to do the same. can toxik do that?

    thanx guys 😀

    The tips posted don´t work? you tried to track only the corners don´t obstructed for the finger´s girls and use expressions to keep the offset, can work if the perspective shifts is small
