My best bet is that B is metalness and R is glossiness. If you are using it for metalness/roughness - try inverting R and check if it gives better results.
You better post to /r/gamedev for example. /r/askreddit is more about general thought- and discussion- provoking (even if it is dumb thought) questions.
