Can't modify gradient [ and can't apply loopOut() ]
on Feb 10, 2013 at 1:09:17 pm

I made two shapes with Illustrator, copied and pasted in a AE shape layer at different keyframe to animate them.
I can add a gradient fill but can't modify it.
Another problem occur when I try to loop the animation adding "loopOut()"
AE send this error message:
After Effects warning: Bad method arguments: loop is not supported for custom properties
Expression disabled.

Using this expression loop animation but doesn't "pingpong" it:
if (numKeys >1 && time > key(numKeys).time){ t1 = key(1).time; t2 = key(numKeys).time; span = t2 - t1; delta = time - t2; t = delta%span; valueAtTime(t1 + t) }else value

Here is the comp.

You can't manipulate the Path using Expressions directly.

To modify the gradient, Click on Edit Gradient option.

Usually selecting objects whit gradient fill shows a gradient control bar (see red arrow)


When I select my shape this bar doesn't appear. I want to rotate the gradient by 90 degrees.
I tried with Ramp but it disabled the shape stroke.

You change the rotation of your gradient by editing the Start and End points within "Gradient Fill 1".

Yes but I don't understand why I can't directly control the gradient

For your wave animation, why don't you precomp the wave and apply time remapping to one cycle of the wave. Then you apply a loopOut("pingpong") expression to the time remap keyframes.

I did it here: 5422_5421gradienttimeremap.aep.zip
