Summary

We looked at the detail layer stack and the two types of detail layers (Grass Billboards and 3D Objects). We went through each tool available to Detail layers; brushes, importing, and procedural mapping using distribution masks. Finally, we had a quick look at blending and the issue of baking shadows from trees onto terrain using object layers.

In the next chapter, we look at adding water features such as rivers, water planes, and a look at road building.
