White line appearing between objects

[q_Link0_p]

I've been working on a simple motion graphics project, and I've noticed some nasty 1px wide white trim around my shapes:

It is not very apparent at first, but if you zoom (or view it on a large screen), you can notice it very clearly.

And the thing is that it is not going away if you increase rendering quality or export project.

That is very strange considering also that my original illustrator vector designs does not contain the same issue no matter how far you zoom in (and yes, I know that it rasterizes it all the way while zooming)

(original vector design)

How do I get rid of those lines?

Also, shapes have been exported with just importing vector files, right clicking and choosing "Create shapes form vector layer".

You need to add a matching 1px stroke or something to fill the gaps. AE does not have an "overprint" setting like it is used in Illustrator.

AE is a video software. It does not work similarly to print solutions. When you zoom in, you will not see a pristine image. Instead you will see what you should see, pixelation. Learn to view AE at 100% resolution, at full quality setting in order to ascertain issues with it. Viewing the Viewer Panels at higher than 100% resolution is pointless and AE rightly tells/warns you that pixelation artefacts will occur at such a resolution.

I hope this makes sense.

I have said it previously,

I know that illustrator and AE are completely different in their rendering techniques, and that AE is pixel based instead of "infinite" vector rasterization that can be found in illustrator.

That's not the point.

Actually, I have noticed that this is due to anti-aliasing artifacts, because  when I disable it on those  objects, white line disappears.

But, disabling AA is definitely not optimal.

I do not know any way to change default AA technique to something more advanced to resolve this issue.

Changing renderer to ray-cast and changing AA withing ray-cast properties made no visible difference.

I also have noticed that CC Vector Blur resolves the issue, but it introduces (as name suggests) blur.

P.S. putting 1px stroke seems janky to me, especially for complex shapes with multiple paths

Do you see the white outline around your imagery if you place it over a black Solid/Background?

[q_Link0_p]

No. It only occurs between two vector objects (on their edges, to be specific).

[Roland Kahlenberg]

Then make one of the two vector objects black - see if the white outline is apparent under this scenario.

[q_Link0_p]

Unfortunately it does not disappear. If anything, it becomes worse because of contrast differences (black shape fill and white artifact)

[Roland Kahlenberg]

White on black (black on white) and you continue to see a white outline. Something impossible or weird is happening. Perhaps you can post an image, at 100% scale for us to look at?
