OK sorry to keep bringing this up but I've figured out= the problem, even if I haven't solved it. I think it makes an easier q= uestion to ask.

Here is my current progress, and in fact= orientation is more important to me than position anyway.

p=3Dtransform.orientation;
x=3Dp[0];y=3D= p[1];z=3Dp[2];

minx=3D0;miny=3D0;minz=3D0;

slider=3DthisComp.layer("CAM CONTROL").effect(&= quot;CAMERA SHAKE")("Slider");
x=3Dlinear(slider,0,100,minx,x);
y=3Dlinear(slider,0,100,min= y,y);
z=3Dlinear(slider,0,100,minz,z);
[x,y,z]

So with this expression, 100 is full wiggle, and 0 o= n the slider is no wiggle. The problem is that, at 50 on the slider, all of= a sudden the values on a rotational scale of 0-360 are cut in half. So tha= t instead of wiggling slightly from zero to 359.8, it wiggles from 0 to 179= .4 in the same span of time. This is not useful. The problem is that orient= ation loops back from 360 to 0 with the original camera wiggle keyframes va= lues.

is there a way to translate those 0-100 values from the= slider to the 0-360-0 degrees orientation uses?

Now I'm trying to do = the same for orientation. A bit trickier. This is as far as I got, but the = output values are definitely not scaled versions of the original values wit= h this. It jumps by much bigger chunks and flips the camera around the axis= when this is applied to orientation keyframes. Any idea what I'm doing= wrong?

p=3Dtransform.orientation;
x=3Dp[0];y=3Dp[1];= z=3Dp[2];

minx=3D-360;miny=3D-360;minz=3D-360;

y=3Dlinear(slider,-360,3= 60,miny,y);
z=3Dlinear(slider,-360,360,minz,z);
[x,y,z]=

Is this what you mean?=C2=A0

Not even su= re this is possible. But say you have an object on a motion path with hundr= eds of keys (not able to be reproduced by expressions).

Sort of like scaling the entire motion path of keys in one o= r all directions, but tying that to a slider, so that when the slider is at= 0, there is no motion. ie it clamps all values to 0.

There is probably an easier way to do this but I was wondering if this= it was possible like this. Thanks,
