Atlas texture settings to prevent distortion of scaled down sprites?

[Fordeka]

Basically I want to create thumbnails of full size sprites by just scaling down the full size sprites (so I can use the same image in the atlas for both sizes)- it looks fine on my PC but when I build to an iPad 2 there are severe artifacts around the edges of the scaled down sprites. Is there any way to get around this problem?

That's caused by texture filtering and not much can be done about that. I suggest creating thumbnails dynamically if possible -- or just having two atlases -- one with the original large images, and another with thumbnails.

It actually turned out to be caused by sandwiching it between sprites from a different atlas- fiddling with the depth seems to have fixed it but there doesn't seem to be a way to have a sprite on top with alpha blend onto it without the distortions happening. If the sprite isn't on top it is distorted.

A pic would help.
