NGUI incorrectly adding shadows to transparent pngs?

[patrickkidd]

I am adding transparent PNGs to my atlas and finding that NGUI is replacing some of the semi-transparent white around the outsides with a dark color, which makes it look like a shadow. Is there any way to get NGUI to use the exact pixel data in the image to it looks the same as the artist designed it?

I've attached 2 of the originals with white highlights around the top edge, the intended noisy-white background image, and the generated atlas texture with the white highlights replaced by darker highlights as generated by NGUI.

Thanks!

Tested it, can't see the problem:

You need to use Unity 4.2+ if you're using PNGs, and have "alpha is transparency" checkbox checked on texture import settings.

PNGs treat transparent pixels as white color by default.

I upgraded to 4.2 and that fixed it. Thanks!
