Apply LOD on cloned meshes

[RavenLee]

Hi guys,

I have a problem of adding LOD meshes to a cloned meshes

Babylon.js Playground

I tried to add LOD meshes to the cloned one and also tried add cloned LOD meshes to the clone in PG, but the privous one seems does not work. Is there any more efficient way to implement cloned LOD meshes rather than duplicate all LOD groups? Since I would like to go further to clone the meshes which contain different skeleton animations and have multiple characters, so it may be a little bit different situation from the following topic.

Instanced Meshes As LOD Meshes

Yo @Deltakosh … There seems to be a problem with instanced meshes as LOD meshes. You fixed this issue once before for instanced meshes coming from GLTF. In the GLTF Parser all nodes in the the GLTF callbacks are Babylon.Mesh. When setting up LOD and the meshes you use in the add LOD level function call is actually an InstancedMesh the LOD does not work properly. I setup a few playgrounds with a demo cliff rock mesh, that has different colors for the LOD so you can easily see the different LOD…

Appreciate for any suggestion.

To me your PG does work in this regard, knot0000 is a clone and has cloned LOD levels (knot0001 → knot0003).

It’s knot000 that does not work, but that’s because you did not assign LOD levels to it.

Each mesh that needs LOD levels must have LODs assigned to them and a mesh used as a LOD can only be used once, that’s a feature of the system.
