gltfpack is very strong, so I want to use it to support meshopt, meshquan, etc.
But the gpu-instantiated components will disappear when I rotate the model in cesium.
Why?
PS:3dtiles(1.1), cesium(1.99), the gltf support the following extensions:
EXT_structural_metadata,
EXT_mesh_features,
EXT_instance_features,
EXT_mesh_gpu_instancing,
EXT_meshopt_compression(gltfpack),
KHR_mesh_quantization(gltfpack),
KHR_texture_basisu(gltfpack),
KHR_texture_transform(gltfpack)
