I'm brand new to working with three.js and I'm trying to achieve a transparent background for the smoke canvas overlaying the image. Currently, the canvas is positioned behind the image as shown in the CSS below.
canvas{
position: absolute;
z-index: 2;
top:0px;
left: 0;
}
I'm struggling to figure out how to remove or make the black background of the canvas transparent. Could you take a look at my demo linked below?
To achieve a see-through background, you have the option to include the alpha parameter when creating an instance of the WebGLRenderer.
var renderer = new THREE.WebGLRenderer({ alpha: true });
If you want to set the background of your scene in Three.js, you can simply use the scene.background property. There's no need to add extra HTML elements. Just assign your texture to it like this:
scene.background = texture;
Check out this CodePen example for reference.
