How to avoid it, with somekind of spacing? Pixel margin don’t help too :confused:

maybe

  • disable mipmapping
  • scale uvs down few pixels
  • in image editor copy each tiles edge pixels and paste 2 times away from the edge, best option in my opinion, bit tedious tho, and your image size increases.
