As a Roblox developer and player, it is currently impossible to tell apart the Ice, Plastic, and SmoothPlastic materials when Brightness is set close to 0. The Metal material similarly faces this issue, but at least it makes the part darker.
If Roblox is able to address this issue, it would improve my mining game as it would allow players to clearly, quickly, and easily identify different types of ores. Simply raising the brightness up is not a feasible solution as it would severely ruin the atmosphere of my game.
