Hi,

I am working on an web application (angular and babylonjs) that will simplify my work and I get an error when I try to hightlight a mesh when I hower on it. Interest thing is that when I “console.log (hightlight)” is not undefined , but it doesen’t work properly.
It’s not worth it to provide a palyground because in playground it works.
I wil provide some screenshots.

because onPointerMove is continuous running :roll_eyes:

InstancedMesh (not of type Mesh but AbstractMesh) is missing certain properties to work correctly with a highlight layer.
