Hello, I’m new to three.js. How does that possible if my mouse moves to the ball, it changes the texture instead of changing the color?

Because I saw the document, the methods only setColorAt and setMatrixAt can control the ball, how do I change the texture? Thanks.

if you check how [those methods](https://github.com/mrdoob/three.js/blob/c7d06c02e302ab9c20fe8b33eade4b61c6712654/src/objects/InstancedMesh.js#L94) work, you’ll see that they just alter the values in attributes, while textures end up being set via uniforms. however, you could have an attribute of indices into a texture atlas, for example. in simpler terms, it not quite possible but you can fake it.

Thanks, is there any sample code I can reference?
