Learn surface materials with StandardMaterial3D.

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;

Exercise Create Metallic Material

Set mat.Metallic to 1.0f and print it with GD.Print("Metalik: " + mat.Metallic);.

Show example 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);
    }
}

Test yourself

Which property determines the primary base color of a material in Godot 3D?
- Emission
- AlbedoColor
- Roughness
- NormalMap
Show answer

AlbedoColor — AlbedoColor defines the pure base surface color of the material independent of reflections.

Set Metallic Ratio

materyal.____ = 1.0f;

Show answer

materyal.Metallic = 1.0f;
