While the premise of making your own PBR textures is a very neat one, and although you clearly state that you aren’t trying to deny anyone’s right to have an opinion on this matter, this kind of post still leans on the dismissive side of people badgering Roblox on what materials should be added and how some should be modified.
If anything, I’d think this would be a poor thing to mention currently in regard to the fact that Roblox is still working out the new materials. Enough has been said about the materials presented already and, frankly, there’s already a general consensus as to what Roblox should do at this point with the materials they made.
The issue here is that you’re basically watering down this whole debacle of concern over detail and general appearance with the whole “Well if ya’ don’t like it, then [insert less convenient to mildly inconvenient alternative]” gimmick.
I do understand where you’re coming from, the unfortunate issue is that this whole schtick doesn’t contribute a whole lot to what Roblox could still do with the materials they are currently working on.
My advice? Keep it to yourself until AFTER Roblox is done doing this stuff, then you can go ahead and tell this to people who still don’t like the new materials.
