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 - Forest/Jungle Floor
1 - a light broken earth with a smattering of foliage for making paths.
2 - Dark earth, like as found on forest floors. *Note, texture only 512x512
3 - Beach sand.
4 - Moss covered rock face.
All art is custom or was freely obtained with the appropriate licenses from public domain for commercial use.
