By using the command Mesh.clone();, it is possible to duplicate the mesh. Upon further investigation, I discovered that both the geometry and material are preserved in the clone. However, my goal is to independently adjust the opacity of each mesh. This leads me to believe that I need to also duplicate the material.
Is there a method to replicate a mesh along with its material in order to have the ability to manipulate the opacity of the new mesh separately from the original?
Correct, the material is shared in cloning processes. To avoid this, consider creating a new material for each mesh and transferring values from the existing material. This may slightly increase memory usage but ideally should not impact framerate.
An alternative approach could be:
let newMesh = new THREE.Mesh(
oldMesh.geometry.clone(),
new THREE.MeshPhongMaterial().copy( oldMesh.material )
);
This code snippet creates a new Mesh by cloning the geometry and using a new material while retaining values from the original material. Remember to update the material if you modify it post-initialization.
let newMesh = oldMesh.clone();
newMesh.material = new THREE.MeshPhongMaterial().copy( oldMesh.material );
newMesh.material.needsUpdate = true;
It's uncertain whether the same type of material must be used or if automatic conversion to the correct type occurs.
