Hi Steven,
That sounds completely reasonable as a suggestion. The one (minor) callout I’d have is that this could open a can of worms on 2 fronts
1) Clients who already have this in-game and will be suprised by the (fixing) change.
2) Could trigger a scramble for all other materials to be closer to realistic values - especially if there are 2 materials interacting and only one of them has an alteration.
Let me sound out the dev side and let you know
Best
