I made those 30 Seamless trextures my self, so i know they arent out there any where.
They are in 2048 x 2048 NO compression this time, they are all in .tga format, hey was smaller size then i expected after .7z compression, only 800 mb.
If your unsure what texture you need/want, download the *.jpg fole like Ground 021.jpg and see if its some thing you like.
