I've successfully loaded a 3D object model into a three.js scene using the following code:
var skull;
var loader2 = new THREE.ObjectLoader();
loader2.load(
'skull.json',
function(object) {
skull = object;
scene.add(skull);
}
);
Now, I'm trying to figure out how to dynamically adjust the opacity of the model. I have searched through the skull variable but couldn't find any properties related to opacity.
Does anyone have suggestions on how I can achieve this?
In the event that the 'skull' object is represented as a mesh within your JSON file, a simple adjustment like skull.material.opacity = 0.5 would suffice. Sometimes, a 3D model file may consist of multiple objects, requiring traversal through them:
skull.traverse((node) => {
if (node.isMesh) {
node.material.opacity = 0.5;
}
});
For more information, refer to the documentation for THREE.Material and THREE.Object3D. This code snippet is designed for three.js version r91.
