I didnt really make the textures. Just used ones found on the net... I would post larger ones but would just as easy for anyone to go to the site here posted by ello.

Then you can pick between quite a few texture images in high res format. Crop out a section accordingly... 256x256 for example and use it as the new texture.

If theres enough interest I will do it but figured it be better for everyone the other way since theyll have a huge choice between textures ... The images are large enough to crop a few textures out of them. So you could create a few variants of the same type of rock...

I went with small textures to decrease the file size... but as I said if theres enough interest I will gladly whip up a few new textures for them.
