Hi there, it’s really easy to fix, all you need to do is just turn OFF “Billinear Filter”, in order to do so, go to the iredit-irrlicht properties, and select the plane mesh in the irrlicht/irredit properties, go to materials tab, and turn OFF the “Billinear Filter”.
And these artifacts will go away from the top of the sprites, I did have mentioned this a few times in some of my videos, but I don’t remember exactly in which one.
Anyways, I hope the extension will be helpful to you:)
