Do Cube cameras / WebGLRenderTargetCube support texture encodings when writing/rendering?

Hi,

We’re trying to have HDR cubemaps so I tried setting the texture encoding of the rendertarget used by a cubecamera to RGBEEncoding, but getting weird results (as if it were decoded incorrectly, which might mean that it was not written with that encoding in the first place). RBGDEncoding does seem to work but just makes everything look much darker.

Thanks!
