Wiggle rotation not following anchor point

[Anoeek]

Hi,

I am trying to apply a Wiggle - Rotation effect to an Illustrator asset layer. However, if I do so, my layer will wiggle all over the place in stead of rotating around it's anchoir point (which I've placed in the middle of the layer). The layer is not parented to anything nor does it have any childs that can interfere somehow. 

If I remember correctly from years ago when I used this effect, it is supposed to wiggle around its anchor point, right? So what am I doing wrong here?

Without specific info about your setup, a screenshot and the expression code nobody can tell you much. The most likely cause simply is that your AI file has invisible content which contributes ot its layer size bounding box, meaning wherever you placed the anchor point isn't really the center. Likewise, of course things like using continuous rasterization, 3D switches and effects would affect the outcome.

Of course, the answer is usually super simple.

It was the continuous rasterization. I had turned it on by default, and didn't think of it when applying the effect. When I turned it off, everything behaved as expected.

Thanks!

If wiggle is added to rotation then the rotation value will wiggle. If you add it to Anchor Point or Position then the layer will move around in X, Y, and Z if the layer is 3D.

Select your layer, press UU to reveal everything modified on the layer, Scrub through the layer and you should only see rotation values changing. If you do not see Position and Anchor point then the position is comp center and the anchor point is layer center. If you don't see either of them and the layer is not rotating the way you want it to then you'll need to move the anchor point.

If you can't figure it out embed a screenshot of the entire UI with the modified properties of the problem layer revealed. Use the Toolbar to embed the screenshot so we can see what's going on.

Are you applying something from the Effects and Presets panel? If so, it's probably not really what you want. Making your own wiggle expression on the rotation parameter is probably the best way to go.
