Hey guys,
the image was fine, no white lines in the ai file or rectangles underneath it.
I figured out a workaround, i just duplicated the layer in ae and put the third option on the quality and sampling swith, the pixelated straight line. Now the lines are fone, since they are transparent.
I know this isn’t the smoothest solution, but i works for now.
I could imagine that merging all the layers in ai and creating a one layer graphic would maybe work too.
Thanks for the help guys
