what is the difference of the 128x128 textures and the 512x512 textures?
if there is 128x128 textures there would be no need for 512x512 textures right?
can anyone answer this question?

The resolution

^ where did you get your brain?

Bitch are you fucking retarded? the difference between them is the resolution, you just can't think right.

youre both fucking retarded.
karstonators a dick and smosh is just dumb.
simple google search would have solved this befor you asked it.

A 512x512 head has 16x as many pixels as a 128x128 head, which means you have the opportunity to wear a much higher quality head texture.

thanks for explaining
