> Hello, Is there something mystery with InstancedMesh? It’s working perfect until it went to disappeared when camera position at -100 and 300 neither x, or z. Feel like weird there. I’m using React Three Fiber (r3f), tried both hooks from drei and r3f but still the same. I was think maybe wrong with camera or gl settings, but when I try with normal, non-instanced mesh and it’s not disappeared no matter how far camera goes. I wonder there is a bug or because I missing something? Please point me…
