After slicing the FBX model with cesiumlab, I used 3dtiles to load and display it in cesiumforunreal. I found that the instantiated model sliced as i3dm could not be displayed in the scene, but it could be successfully loaded in the web browser. I can’t find the root of the problem, or whether I should modify some parameters to break this limit. I also want to ask whether there is a suitable solution for all leaders. be deeply grateful!
Currently there is a ticket open to support i3bm, Support i3dm tile payloads · Issue #671 · CesiumGS/cesium-unreal · GitHub
I am looking for this feature aswell, or really support of the gltf extention - EXT_mesh_gpu_instancing
