This high quality art has been purpose tuned for building levels in game-guru. Unfortunately there is some minor stretching so it does require some playing around with the heights of the rocks involved when doing vertical walls. This is a result of the way the engine attempts to override the texture.
The textures included:
Default - Cracked dirt
1 - A nice brown brick tile.
2 - A marble brick, perfect for old ruins.
3 - The same marble brick, coated in blood. Fades superbly with alt-texture 2.
4 - A semi-mossy stone labyrinth-style rock.
