StandardMaterial3D and Surface Materials
In Godot 3D, the physically-based (PBR) StandardMaterial3D resource is used to define surface characteristics. This material computes how light interacts with surfaces and is applied to an object by assigning it to the MaterialOverride property of a MeshInstance3D node.
StandardMaterial3D mat = new StandardMaterial3D();
meshNode.MaterialOverride = mat;Albedo and Metallic Properties
While AlbedoColor determines the base color, the Metallic property specifies the surface metalness between 0.0 and 1.0. A value of 0.0 represents dielectric surfaces like plastic or wood, while 1.0 represents pure metals like gold or steel. Surface roughness is managed by Roughness.
mat.Metallic = 0.8f;
mat.Roughness = 0.2f;Practice Create Metallic Material
Set mat.Metallic to 1.0f and print it with GD.Print("Metalik: " + mat.Metallic);.
Starter code
using System;
public class StandardMaterial3D
{
public float Metallic { get; set; } = 0.0f;
public float Roughness { get; set; } = 0.5f;
}
public static class GD
{
public static void Print(object message) => Console.WriteLine(message);
}
public class Program
{
public static void Main()
{
StandardMaterial3D mat = new StandardMaterial3D();
// Metaliklik oranini 1.0f yap ve ekrana yazdir
}
}Sample solution
using System;
public class StandardMaterial3D
{
public float Metallic { get; set; } = 0.0f;
public float Roughness { get; set; } = 0.5f;
}
public static class GD
{
public static void Print(object message) => Console.WriteLine(message);
}
public class Program
{
public static void Main()
{
StandardMaterial3D mat = new StandardMaterial3D();
mat.Metallic = 1.0f;
GD.Print("Metalik: " + mat.Metallic);
}
}Expected output
Metalik: 1
Questions and answers
Review the lesson questions together with their answers. To test yourself, solve the lesson interactively.
1 Which property determines the primary base color of a material in Godot 3D?
- Emission
- AlbedoColor Correct answer
- Roughness
- NormalMap
Explanation: AlbedoColor defines the pure base surface color of the material independent of reflections.
2 Set Metallic Ratio
materyal.____ = 1.0f;materyal.Metallic = 1.0f;Explanation: The Metallic property is used to configure the metallic reflection ratio of the surface.
