even though you can now get 256, 512 texture heads you still have to put in a disclaimer when you show them to people on the forums, just so they dont get confused......
and something else, i personnally think that when you put a texture on that you uploaded as 512x512, even when you have a 128x128 texture, it still looks better than if you uploaded it on as a 128x128, im not sure, but it just looks that way to me.
