RayTracingShader.shaderKeywords

Description

An array containing names of the local shader keywords that are currently enabled for this ray tracing shader.

Shader keywords determine which shader variants Unity uses. For information on working with local shader keywords and global shader keywords and how they interact, see Using shader keywords with C# scripts.

Note: It is more efficient to use enabledKeywords, which returns an array of LocalKeyword structs.

This example prints the names of all currently enabled local shader keywords for a ray tracing shader.

using UnityEngine;
using UnityEngine.Rendering;

public class Example : MonoBehaviour
{
    public RayTracingShader rayTracingShader;

    private void Start()
    {
        foreach (var localKeywordName in rayTracingShader.shaderKeywords)
        {
            Debug.Log("Local shader keyword " + localKeywordName + " is currently enabled");
        }
    }
}
