I would like to disable the near plane clipping from my ArcRotateCamera so I will no longer be able to see through meshes like in the following screenshot:
That was the issue.
I’m using InstancedMesh so you need to set the material property on each instance not just on the source mesh. That’s why it wasn’t working when I first tried it!
material.backFaceCulling = false;
Also please note that the value should be false, not true.
