Hello! I was wondering if there was a way to either: create an Octree manually, such as var octree = new BABYLONJS.Octree(64, 2); and run interesect(), etc calls from it after manually populating it with meshes OR filter out the meshes (by name/id?) when calling scene.createOrUpdateSelectionOctre…

That looks very useful, thanks. Is there a way to remove a mesh (so the inverse of addMesh)? edit: duh [image] Octree | Babylon.js Documentation Octrees are a really powerful data structure that can quickly select entities based on space coordinates. [API]

Sorry another question. is it possible to add instances to an octree using addMesh()?

Yes, it should work, as addMesh is taking an AbstractMesh as its parameter.
