Looking to buy texture packs. What is difference between these? I mean aside from being different sizes? Does it allow for more detail or?

i mean it goes hand it hand if you have a bigger size you have more pixels to work with so yes 512 can be more detailed than 128

512x texture gives you a better and clearer texture and costs way more than 128x textures. I am selling full 512x body+joints for USD. Pm me if you are interested.
