I made android unity project from window pc, then I want to make iOS build,

so I copied that project to mac mini, opened it from iOS unity 4.2.1,

all textures become blurred and seems to be dirty.

Why and how to fix?

Thanks.

solved, I used ezgui, so I re-set ezgui’s material texture’s setting, all become normal.
