Battlefield grass textures?

[PROMETHEUS]

The fact is that there are already in the battlefield folder 512 512 textures , Should I do them in 1024 1024 ? I haven't noticed when I did so a sharper ground tough , could it be possible to a text file that needs to be edited?

can u post a pic of sample of difference between the ground texture u did and the ca one overwritten?

For example this is the size of the Oz_grass texture for alpine climate summer , but how many does it uses ? becouse I saw several textures , some where in 256 , others like this in high res , I am not sure the game uses it does it? if so for what?
