Custom Procedural Textures

// Create a custom procedural texture with a fragment shader
const customProceduralTexture = new BABYLON.ProceduralTexture(
    "customTex", 
    512, // Size
    "customShader", // Shader name
    scene,
    null,
    true, // Generate mipmaps
    true  // Is fragment only
);

// Set shader parameters
customProceduralTexture.setFloat("time", 0);
customProceduralTexture.setVector2("resolution", new BABYLON.Vector2(512, 512));

// Update time in the render loop
scene.onBeforeRenderObservable.add(() => {
    customProceduralTexture.setFloat("time", performance.now() / 1000);
});
