CC Repetile creating a thin gap

Just ran into this problem. It doesn't seem to happen when you import directly from Illustrator, especially if you line things up with the pixel grid in Illustrator as suggested. When it's not lined up to the pixel grid there's a really faint line.

It only seems to happen with editable vector layers. So, layers imported from Illustrator that have been converted to shapes, imported using Overlord and shapes drawn in After Effects. Each of them improve (very slightly) when they are exported, but not enough to fix the problem every time. In my specific case the gap was giant, not just a couple of pixels, so that wasn't helpful. 

This doesn't solve anything it's just information for anyone who ends up here. Maybe it will be helpful to someone.  

I have a Composition with A Precomp Of AN image Inside it. Above I place AN adjustment layer with `CC Repetile` I too get thing gaps between the tiles.I tried scalling resizing images, the precomp etc with no success. Funnily If I scale the precomp to between 100.0 & 100.4 the gap seems to narrow. Then once past 100.4 it grows back to what it was at 100.
Note this was with `CC Repetile on an adjustment layer above the image i want to extend. 
If i apply the `CC Repetile` directly to the precomp layer it goes away! there. I don't know if that helps adobe look into solving this if they are interested. Hopefully. As I like the effect on an adjustment layer because i planned on rigging my project up so users can use opacity with a dropdown to select images, below it. But I;ll do that anyway but apply the `CC Repetile` to each image layer. Annoying but a suitable workaround for me at the moment

Hi Ashik,

Yes this is an unsolved problem, one work around I have done, is once the reptile is done, is to copy the layer and place it under the other ans shift it slightly over which covers the gaps. This does not work for all types of comp work, but its a quick fix in some instances.

Late to this thread, just ran into this in v23.6.2. Have not checked v24 or the Beta yet.

I tried all the methods listed on the page; Mask+Repetile worked at first but my shape layer is moving and I needed motion blur, which added the gap right back. So what finally worked was to pre-comp the shape layer and make sure it was cropped right to the artwork with no gaps on the edges, then Repetile it back in the main comp and add the transform+motion blur there. 

I met some of the After Effects team at MAX, I might try to bring this up as a bug to fix next time we chat.

If you are having a problem with Reptile when using AI files, then the problem is in the AI file. The artwork does not line up to the pixel grid, so the edges are interpreted.

The fix is to open the Illustrator artwork, go to the View menu, turn on Pixel Preview, and set the project to Snap to Pixel. Now set the viewing magnification to 400 or 800% and fix the alignment of all the horizontal and vertical edges in the artwork. That should solve your problem.

Fix the artwork and you fix the problem.

I have the same issue with MotionTile and RepeTile and to fix it, I precomped (nested) the video layer (it could be any layer) and applied the Transform effect with Scale set to 101% (it won't show since the layer is already at comp size). Then in the parent comp I added the RepeTile effect and that got rid of the black/blank borders.

Adobe, PLEASE FIX THIS. I see posts about it from 2018. Seriously no new features just focus on no crashes and proper workflow.

Not sure why this problem occurs, I'm getting the same problem with my own AI files converted to shape layers. Anyway, you have an alternative. Shape layers can be cloned using the repeaters. If you expand your shape layer, select the content. and with that little drop-down at your right select repeater. The repeatear lets you create copies of your shapes and move them to the right avoiding that cc repetile issue.

I will try a couple of things with AI files and write later on.
