You can paint these and additional landscape layers by hand, or apply masks from World Machine (or any other terrain generator). You don't need to edit complex shader systems – just link the textures and start making your awesome levels!

 

The package includes production-quality assets: realistic grass, translucent water with distortion and caustics, 7 tree types, 6 types of bushes, 5 types of flowers, 3 different stones and a blowball effect. A sample scene to get started is also included in the bundle.
