Figured it out. AE doesnt store variables over time apparently. So a modulus function works instead just fine I think

spd = effect("Slider Control")("Slider");
angle = effect("Angle Control")("Angle");
d = spd*(time-inPoint);
r = degreesToRadians(angle);
x = d*Math.cos(r);
y = d*Math.sin(r);
value + [x%1280,y%720]

Fantastic, found this incredible post here

Apply this expression to your orientation and it will nullify any 3D rotation inherited from the parent.

Not entirely sure how it works though!

u = fromWorldVec([1,0,0]);
v = fromWorldVec([0,1,0]);
w = fromWorldVec([0,0,1]);

sinb = clamp(w[0],-1,1);
b = Math.asin(sinb);
cosb = Math.cos(b);
if (Math.abs(cosb) > .0005){
c = -Math.atan2(v[0],u[0]);
a = -Math.atan2(w[1],w[2]);
}else{
a = (sinb < 0 ? -1 : 1)*Math.atan2(u[1],v[1]);
c = 0;
}
[radiansToDegrees(a),radiansToDegrees(b),radiansToDegrees(c)]

Ok, when I try rotating more than one axis, this technique falls apart. Just inverting the rotation against the null doesn’t seem to work.. I guess the math isnt right!

Any ideas?

Cheers

[Jim Johnston]

Thanks very simple, just invert the parameter!

I used:
-parent.transform.xRotation

Cheers

If I were you I would send the printer two files, one print quality .pdf for printing, and another pdf with instructions of how you want the print to be folded, possibly with illustrated instructions and measurements of where the folds are. Good luck!

Hi Karl,
What you need to use is the ‘Star Tool’ which is bunched in with the Rectangle, Ellipse tools.
Just click and drag and a star will emanate from that point. Whilst still dragging use your up and down keys to increase or decrease the amount of points on the star. Further more you will want to elongate the arms by distancing the outer points from the inner points, you can do this by holding down ‘Ctrl’ and dragging away from the centre point.
Hope this is clear,
Good luck

Have you tried the [Smallest File Size] preset in the PDF settings dialog? This one usually does too much of a good job by compressing the hell out of any pictures, but you can play about with the compression there to get your desired result.

I think maybe you are working too small.. Although Illustrator is a vector based software, there is a limit to how close you can have two points. So if you reduce a complicated logo to a hundred microns the software will only have so many ‘points’ to place each vector point, therefore it will reposition them giving your logo a distorted look when you enlarge it again. Have a look at what size the document is, enable your rulers too.
Hope this fixes your problem!

Hi Jacob,
Nice looking flowers! I would select your brush strokes then outline them (Object>Path>Outline Stroke)then use the Live Paint Bucket tool for filling in colour.
Hope that works for you!
