Output nodes "usage" section should be more consistent with the 3D preview
I export my textures packed with each channel representing one material properties. It is possible to describe these "usages" in the Output node but the 3d viewer doesn't respect them and only seem to accept a usage that is set to RGBA components.
I'd like the viewer to be able to gather its inputs from my Output nodes usage, even for textures that affect several material properties.
Maybe the last part would be better phrased as :
"I'd like the viewer to be able to gather its inputs from my Output nodes usage, even when a single texture affects several material properties."
