Code is the following const engine = new BABYLON.Engine(canvas, { stencil: true }); const scene = ... const hl = new BABYLON.HighlightLayer("hl1", scene); this._meshes.forEach((mesh) => { this._hl.addMesh(mesh, this._hlColor) }) The problem is that I can not add a mesh to the highlightLaye…

It is by design for rhe same reson that you can not specify the material of an instanced mesh. Basically instances render in one call so you can not individually add them in. Cause we would need to separate the calls and lose the instances advantage. In your Case the easiest is to keep one uninsta…

Thanks. But the one that should be highlighted changes with by a user interaction. Like when the user points with the mouse to a mesh. And they are 500 of these meshes on the scene. From my limited knowledge about instancing I though that it is the geometry that is shared, but the instances could v…

You could use different sets of instances and highlight the full set at once ?

Yes. That’s a good idea. The reason I have not though about it is because the InstancedMesh(es) get created by GLTFLoader and I have no control over which meshes are InstancedMesh and which are not.

Good afternoon. I bring up an old topic so as not to create a new one (I apologize, if necessary, vice versa). I had a similar problem, in my development I plan to use a lot of models, so instances were chosen for optimization, but when I tried to use “HighlightLayer” highlighting, I ran into the sa…

@kekeqy feel free to improve it, it is all open source, you can make a PR for it. @Lazarus_Rainhard the main issue boils down to the underlying tech. there is not much to do here. Maybe you could rely on a custom shader where you would use a custom attribute to enable/disable highlights in the effe…

oh, I read the introduction to shaders and it’s too early for me, it’s difficult… [image] Introduction to Shaders | Babylon.js Documentation Dive deep into the inner workings of shaders in Babylon.js. Oh, sad, the backlight looks very good, but I still have t…

In this case the simplest is to keep one none instanced mesh and when you need a highlight, hide the instance to lit, clone it s position rotation scale into the none instanced one and it would visually looks the same

This design is a bit lame, I wish it could be improved.
