Hello, As it seems there were quite a few discussion around highlighting meshes you can find below the solution integrated in standard in bjs: var hl = new BABYLON.HighlightLayer("hg", scene); hl.pushMesh(box, BABYLON.Color3.Green()); Please be aware, the stencil needs to be able in your canvas: var engine = new BABYLON.Engine(canvas, true, { stencil: true }); You can take a look at the result here: http://www.babylonjs-playground.com/#E3D3Y#2 Best Regards,
