Hi I am working with bone manipulation so I am moving the bones of an imported mesh using ImportedMesh.skeletons[0].bones[0].position = another position. it works as expected but I noticed that when my camera is moving or looking into different location the mesh is starting to appear disappear. I am not sure if this is a bug or I am just missing something here. I have a playground that you can take a look. I really appreciate if someone can help me 
One of possible solutions - https://playground.babylonjs.com/#94OCGT#2
meshes.forEach((m) => {
m.alwaysSelectAsActiveMesh = true
})

That’s because the bounding boxes are computed according to the base mesh, not the skeleton / animations (in fact, in case of gltf/glb files, I think the bounding box is retrieved from the file):
Your meshes disappear when their bounding boxes are outside the camera frustum. The simple fix is the one provided by @labris. If you don’t want to completely remove frustum check, you can manually assign bounding boxes big enough to encompass whatever poses / animations are applied.
