How to get MeshStandardMaterial roughness affect envMap from CubeCamera?

I’ve tried to apply roughness to a cubeCamera set as an envMap of a MeshStandardMaterial, but I can’t seem to make it work.

Here is a jsfiddle:
In this example, I’m trying to have blurred reflection on the sphere, but roughness seems to make no difference.

I’ve tried to apply different filters to the cubeCamera, but that either does not change anything, or raises an error like RENDER WARNING: texture bound to texture unit 0 is not renderable. It maybe non-power-of-2 and have incompatible texture filtering. (when the resolution is 128, so it must be a filtering issue).

Does anyone know if this is supported and/or if I’m missing something?

i have this problem,too :sweat_smile:
