Hi,

in my scene, there are instances of several meshes.  
Instances can be identified with isAnInstance.  
But how to get a reference to the source mesh?  
In Api, there is “souce”, also in the debugger.  
But in my script, source is always “undefined”.

Here is a snippet:

```
scene.meshes.forEach(function(mesh){
         console.log(mesh.name + " <= " + mesh.source);
}

```

What am I doing wrong???

THX  
Stefan

Hi @Stefan70 and welcome to the forum.

source only returns source mesh for a clone not an instance

Hi,

i got it, its **sourceMesh** and now everything works fine 🙂  
My Problem was adding a instance to a highLightLayer ist not possible, so i need to add the sourceMesh.
