White 1px lines around (pic included)

[Roosuomi]

Hi

I have a tree. There are no white lines around it. I have adjust the composition background the same color as the three color (pic in the left). But when pre-composite After effects adds these 1px white lines around my tree (pic in the right). Why?

Check the continuous rasterization settings of the precomp and layers inside, as well as your preview resolution. If everything looks good on full res, you are good to go. Don't mind quality drops in half or less resolution.

I also noticed a very thin outline - glitch, when have vector layers with exactly overlaying areas. I always solve this by moving the underlaying path a bit inside.

Check the file in Illustrator. This usually happens when you have layers with identical outlines and the antialiasing accumulates to more opaque values. Inset/ shrink the fill area using the offset path function then. Also check any overprint and stroke stuff. Could be that 0.1 pt stroke you used at some point to fix a gap issue and then forgot about.
