How Can I Change the Background Color in My Three.js Scene?

Customizing Three.js Background

Three.js developers often encounter the issue of adjusting the default black background of their scenes. This can be achieved by altering specific settings within the Three.js framework.

One method involves modifying the following line in the three.js initialization function:

// Initial Default:
renderer.setClearColorHex( 0x000000, 1 );

To change the background to white, use the following code:

// Change to White:
renderer.setClearColorHex( 0xffffff, 1 );

Updated Solution:

According to HdN8, the updated method is:

renderer.setClearColor( 0xffffff, 0 );

Additional Considerations:

To enable transparency in the background, set the alpha value in the WebGLRenderer constructor to true:

var renderer = new THREE.WebGLRenderer({ alpha: true });

Alternative Method (r78 ):

As suggested by Mr.doob, an alternative method for setting the scene's background color:

var scene = new THREE.Scene(); // Initialize scene
scene.background = new THREE.Color( 0xff0000 ); // Set background to red
