I want to share that I found a solution to the backlight problem. The forum previously answered how to deal with a complex model, but the topic is incorrectly named, so it’s hard to find: [Hightlayer issues](https://forum.babylonjs.com/t/hightlayer-issues/31173)

It would be nice if someone adds examples to the documentation (here [Highlighting Meshes | Babylon.js Documentation](https://doc.babylonjs.com/divingDeeper/mesh/highlightLayer) ) on how to deal with highlighting in complex models (and instances at the same time):  
Complex model: [Babylon.js Playground](https://playground.babylonjs.com/#L1NWMH) (from this thread: [Hightlayer issues](https://forum.babylonjs.com/t/hightlayer-issues/31173))  
Instaces: [https://playground.babylonjs.com/#AHP3J7#8](https://playground.babylonjs.com/#AHP3J7#8) (from this thread: [Why can't I add an InstancedMesh to HighlightLayer - #7 by kekeqy](https://forum.babylonjs.com/t/why-cant-i-add-an-instancedmesh-to-highlightlayer/6183/7))
