Don't know about you, but I never seem to be satisfied with how stone looks ...
So I decided to do something about it.
I have created a stone texture that is large enough that it doesn't appear at first glance to have an obvious pattern match, which is very important to me. It doesn't change colour suddenly like some of the more obvious ones, and is neither tan nor grey, but can be used as both (or at least I think so). It's also non-descript enough to pass as a generic stone texture. So in my opinion, a jack of all trades stone texture.
Have a look, and by all means download it and use it. Download the ZIP (there's only one file in it) NOT the screenshot ... Just put the screenshot up so you could try and find the seams before you looked at the JPG ... I have a hard time, and I know where they are. FYI, the screenshot has parts of 6 JPG's in it. There is one horizontal seam and 2 vertical ones ...
I would welcome feedback - positive or negative.
