When the Materialparameters property transparent is set to true in threejs, the object becomes invisible

Currently, I am enrolled in Bruno Simons' class and in the session "Haunted House," he is teaching how to incorporate textures. So far, everything seems to be running smoothly and all the map textures are functioning perfectly. However, when I input the parameter transparent: true, the entire object becomes invisible instead of just removing the excess texture. It seems like the expected outcome is not being achieved here.

If any additional details or parameters are required, please let me know. I'm eager to learn and enhance my understanding of this concept.

Make sure to use a texture with a properly set alpha channel to distinguish between transparent and opaque areas. Opt for a file format like PNG that supports alpha channels and double-check the alpha values in the texture for accuracy.

For the correct blending mode in your material, adjust the settings accordingly in Three.js using the blending property. For transparency effects, consider setting it to THREE.NormalBlending or THREE.CustomBlending and defining custom blendSrc and blendDst functions if needed.

Give this a shot!

const texture = new THREE.TextureLoader().load('your_texture.png');
const material = new THREE.MeshBasicMaterial({
    map: texture,
    transparent: true,
    blending: THREE.NormalBlending,
    depthTest: true,
    depthWrite: false,
});

const mesh = new THREE.Mesh(yourGeometry, material);
scene.add(mesh);
