I'm creating a series of comps with some toon characters created in Illustrator CS6 (saved with no compression), and being precomped and rigged, then used in a larger comp. 3D and rasterization are enabled in both the main comp and precomp.
In Illustrator, I applied an inner glow for some depth to the illustrator layers. However when the camera does a simple z-move, the inner shadow flickers everywhere, like i was animating its offset and opacity properties every single frame. Turning off rasterization in the main comp or any combination in the other comps fixes this, but of course blurs things. The precomped characters are all at 100%, so it's not like I shrunk these down and the details are getting lost like so much judder or thin type scrolls.
Layer styles take precedence I think over anything. If you collapse the transformations it will render out over the animated footage. And I'm guessing it flickers because it can't correctly calculate subpixels...as AE does.
Your solution is to increase your vector's resolution in a precomp. Apply styles inside and don't collapse.
Now use this comp as if your vector was rasterized.
