Instancing is where you take a parent material and make copies of it that have differences within them. This was already touched upon in the Instancing a material recipe in Chapter 3, Opaque Materials and Texture Mapping, but there are a lot of things that can be done with this concept.
In this chapter, we will cover the following recipes:
- Creating snow on top of objects using layering materials
- Changing from a sunny scene to a snowy one through parameter collection
- Changing between seasons quickly with curve atlases
- Blending landscape materials
- Customizing UVs
