Rotate the bulge tool?
Hi
Does anyone know of a way to rotate the bulge tool? I can adjust the horizontal and vertical radius of it, no problem, but I really need to be able to rotate the effect. (Nesting the composition is not really an option).
Can it be done? Or is there a plugin that will do it?
Cheers

If that should failo, you can find alternatives with built-in rotating routines in third-party plugins such as lenscare’s flAir package or BorisFX.

Methinks a master AE Magician should be able to do it with the effect, distortion map, but I’m not clever enough to generate the distortion map to make it work.
Rotating an adjustment with Bulge doesn’t work for me, but rotating “My Layer To Be Distorted” with keyframes gives you the Equal but Opposite of what you want, the Bulge is effecting the layer as it rotates below, so…
Precompose the Adjustment layer and “My Layer To Be Distorted” (select both, Layer>Pre-compose, then Move all Attributes) , then rotate that precomp in a equal and opposite direction, either manually or with this expression on the precomp’s rotation:
– comp(“Comp 1”).layer(“My Layer To Be Distorted”).rotation
This expression comes from pickwhipping the precomp’s rotation to the “My Layer To Be Distorted”‘s rotation (it’s in the precomp) and then putting a minus sign in front.
So animate rotation in the precomp and the Bulge will rotate in the comp the way you want.
Oh, yes, you’ll probably need to go and make that precomp larger (Ctrl K) as when it doing it’s unseen counter-rotation magic, it clips off the edges of the layer, you’ll see.

Another way would be to sandwich the Bulge effect in between two copies of the Transform effect. Use the top copy of Transform to do the rotation, link the bottom Transform’s rotation to the top’s with an expression like this:
-effect(“Transform”)(“Rotation”)

Yikes, why didn’t I think of that? Much more elegant and no precomposing. I don’t use Distort>Tranform enough.

Thanks Dan,
Your suggestion worked perfectly. Thank you for such a simple solution.
