In this chapter, you'll continue working on the same project, adding props and physical objects that can interact with the camera and with the world around them. You'll become more familiar with materials and some of the different options you have when working with them, and you'll discover ways to make your scene more realistic and engaging with complex-looking background objects that render quickly.
Texture face objects and transparency
Fast foliage with billboards
Rigid body physics for interactive objects
Pseudo-instancing for efficient object handling
Working with low-poly collision ...
