Your welcome glad you are enjoying it. I honestly have not thought about the textures. If you are not running this mod from the modhub try it out and see if it gives you the textures you are looking for.

I run this mod thats probably why I never noticed lack of ground textures. If that does not work or give you all the textures you are looking for I'll look into how to add them.
