Bumpiness

• Perturb normals to simulate bumps.
• Compute normals from a height field.
• Sample and blend normal maps.
• Convert from tangent space to world space.

This is the sixth part of a tutorial series about rendering. The previous part added support for more complex lighting. This time, we'll create the illusion of more complex surfaces.

This tutorial was made with Unity 5.4.0f3.
