Rocks - same-same but different

Although my rocks had looked okay in isolation, I was starting to feel that they were too noisy and fussy across the level. I simplified the overall look of the rocks by:

• reducing the number of normal map details
• using a subtler diffuse texture with fewer details
• enhancing the strength of the asset-specific curvaturecavity/occlusion
• bringing the overall tonal balance between lit and unlit closer together

I also reduced the expense by:

• swapping out overlay blends for multiplies
• removing the "texture rotates with asset rotation" stuff (since the textures were now rotation independent)
• simplifying the top-down lighting stuff

I also improved their placement by increasing scale and using fewer pieces to simplify the shapes and create less "clutter".

You may also spot I've been toying with grassy/mossy decals. Still playing with those, I don't expect to leave them as-is.
