Problem with scrolling/fading background using alpha

[DaVeF101]

I’ve created a scrolling 2D game that when you reach a certain height the backgrounds switch using an alpha fade technic… my problem is the background fading develops lines between each sprite, which aren’t visible before the fading starts… see screen shot.

I’ve tried changing Wrap Mode and Filter Mode which makes no difference. Also Mesh Type, when set to Full Rect eliminates the error, but I get lines between the background tiles when no fading (cure one problem, get another).

Any ideas?

Any one?

Lines usually mean the source art is too tightly packed. Try adding some margins of empty space, 1-2 pixels, in the source.
