timeRemap Scripting problems???? Help

[pawmunkey]

I  created a timeRemap script for a characters head (face4) so that it  would show suttle shadows on a characters face when the yRotation axes  is rotated using a null object named "Face Center". When the characters  head (face4) layer is rotated in the negative numbers of the y Axes, his  face disappears after its at -7. Yet, everything seems to work fine  when I go in the positive direction using the yAxes rotation.

The code I'm using is: timeRemap=timeRemap+(thisComp.layer("Face Center").transform.yRotation)/-25;

Can some one please assist me.

Thank you......

How many total frames do you have time remapped? I would leave the keyframed Time Remapping value out of the expression. Say you have 50 frames total. I'd do it like this:

center = 25;  // center frame

(center + thisComp.layer("Face Center").transform.yRotation)/-25;

Thank you for your assistance.

Three (3) frames have been remapped. The center is set at frame 1.

The head is nested in a composition with a total of 8 frames.

I used your code and it yielded better results. Instead of the head disappearing at -5 it disappears at -32 but when the characters head is resting in the center at 0 on the X axes the shadow is no longer centered

What could the problem be once the character rotates in the - negative direction on the Y axes?

Only three frames? Then how about something like this:

r = thisComp.layer("Face Center").transform.yRotation;
if (r < 0 )
  f = 0
else if (r > 0)
  f = 2
else
  f = 1;
framesToTime(f)

Thanks.....

Your 2nd code yields the opposite of your first code. Accept that, once it goes to the positive numbers (r < 0 ), the face disappears.

Dan, you have been a big help. I think I am able to solve the issue. I used my original code but instead of using / -25, I increased it to 360 and was able to see the full rotation of the characters head.

Thank you for your assistance.
