momentarily, if i am not mistaken, we have the option to choose two seperate environments at maximum.
that is, type primary as an enironment that's taking over all aspects of an environment.
and type visible, that is alternatively taking over backplate and/or reflections and/or refractions.
what i would like is 4 seperations.
define an environment that is responsible for gi illumination only, in addition to that a different hdr/texture/color-map for the backplate, an other different one that is being seen only in reflections and a fourth one that is only seen in refractions.
