What are the 512x512 textures for? I bought a set that was 512x512 but I didn't have the 512x512 textures. But, I used them anyway and they looked fine. What would I need the textures for?

They're bigger so they show much more detail. By using 128 or 256, things can be harder to see. They have the same functionality however.

Oh thanks. What if I use a 512x512 texture without the texture item?

u mean 512 texture ART or ITEM? u can't use any art without whole textures(items) u must buy all whole textures then u can buy texture set art(flats not items) then upload the flats to the whole textures from: press "Shop" in top then at left find textures

If you have a 512 art, you can equip it on any size texture item. Although a 512 texture on a 128 texture item will be blurry/pixelated.

Think.
With your textures it put pixels on your toris head and those pixels are colored ofc and that forms the picture in your head.

128x128 have 16384 pixels to color.
512x512 have 262144 pixels to color so you can make it lots more accurate.

So, I have to resize it now.......

You can resize it but it won't look as good as a texture that was made originally in 512x512.

Alright then. Thanks for the help.
