Blender made grass and crates. The grass is made with a hair particle system and the crates are actually just cubes, no height normals. All of the detail is hand textured in photoshop.

Grass is thinner in width but denser here, a less preferable grass variant.

Here is a LOD example of the barrel, frontmost is a highpoly, second is simply adding the ridges in, and the back is the cube.
