[TeamTreeHouse] Materials in Unity

124-minute Game Development Course

About this Course

In Unity, and in computer graphics in general, a material describes the surface appearance of a 3D model. Materials can create the appearance of surfaces like wood, metal, fabric, and more. In these lessons, we’ll learn how Unity implements physically based rendering, which is rapidly becoming the de facto industry methodology for creating dynamic and realistic textures.

What you’ll learn

• Materials
• Textures
• The Standard Shader
• Physically Based Rendering

Understanding Materials
In Unity, and in computer graphics in general, a material describes the surface appearance of a 3D model. When a model is first created in a 3D modeling application like Maya, it doesn’t have any kind of surface appearance – it’s just a uniform blank canvas that’s made out of polygons. However, in the real world, an object might be made out of metal, wood, fabric, ceramic, and more. Materials allow us to create a huge variety of surfaces.

Textures in the Standard Shader
The Standard Shader is Unity’s implementation of Physically Based Rendering. It has several inputs that help describe the color, smoothness, and bumpiness of a surface. Each of these inputs accepts a texture map for more fine-tuned manipulation.

Additional Textures in the Standard Shader
Typically in the Standard Shader, the texture slots for albedo, metallic-smoothness, and normal will be filled. However, there are additional texture slots in the Standard Shader which allow you to add more detail.

Scripting Materials
The material properties of the Standard Shader can be accessed via script. This makes it possible to animate materials and adjust their properties over time.
