Chris I think so, exactly. Now to translate that expressio= n into 3D array I would write it like this? Look right?

=

x=3Dp[0];y=3Dp[1];z=3Dp[2];

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

slider=3Deffect("Amount= 0-100")("Slider");

y=3Dlinear(slider,0,100,miny,y);<= /div>

[x,y,z]

x=3Dl= inear(slider,0,100,minx,x);

[x,y]

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,
