k thanks, but i need screens to see how is the quality ^^

depends on the texture you want,you can't just put plain textures there,look at sets sold in the shop section,should help.

full 256 cost ~150k

Maybe this might help you. But no 256 screenies. Only 512 and 128.
128 has the worst resolution,but it's the cheaper one than others resolution. I'd say 256 is medium quality,and 512 being the highest quality.

You can buy Full 256 with price 130k - 150k. Depending on the buyer.
