Summary - Material

Reinforce material usage with a summary task.

Summary: Material System

In this module, you mastered all pillars of the PBR material workflow. While a Shader directs GPU operations, Albedo sets base color, Metallic dictates conductivity, Smoothness controls gloss, and Normal map simulates micro-relief.

// PBR Material summary structure:
// Material -> Albedo (Color/Texture) + Metallic + Smoothness + Normal Map
// MeshRenderer.material = customMaterial

Synthesized materials bind to 3D meshes via MeshRenderer to produce compelling visuals.

Exercise Print complete material profile

Define albedo ("Red"), metallic ("1.0"), and smoothness ("0.7"). Print Material Albedo: Red | Metallic: 1.0 | Smoothness: 0.7 to the console.

Show example solution

using System;

class Program
{
    static void Main()
    {
        string albedo = "Red";
        string metallic = "1.0";
        string smoothness = "0.7";
        Console.WriteLine("Material Albedo: " + albedo + " | Metallic: " + metallic + " | Smoothness: " + smoothness);
    }
}

Test yourself

What settings should be configured on a material to produce a polished and shiny red metal?
- Albedo black, Metallic 0.0, Normal Map disabled
- Albedo red, Metallic 1.0, Smoothness high (e.g. 0.9)
- Albedo transparent, MeshRenderer disabled, useGravity true
- Albedo blue, Metallic 0.0, Smoothness 0.0
Show answer

Albedo red, Metallic 1.0, Smoothness high (e.g. 0.9) — Red color comes from Albedo, metallic nature from Metallic = 1.0, and high gloss from high Smoothness.

Assign shared material

renderer.____ = baseMat;

Show answer

renderer.sharedMaterial = baseMat;
