I need a Little help fixing problems where artifacts or seams appear on my mesh at distance, It only happens when I use the texture from Blender but if I use a blank white texture the seam disappears. First I thought it was edge padding but there are no seams up close on the model, only as I am further away. By the way these are all made in Blender and imported into to unity free 4.6
Might be an UV issue. A simpler solution may be to disabe mip-mapping for those textures.
