It looks like it was done in Roblox, by increasing the reflectance and adding Blockland stud decals.
I played ROBLOX once. For like ten minutes. Four years ago. I wouldn't know.
This is so easy to do. roblox + blockland decals. Now what needs to happen is badspot needs to add a reflectancy option to the wrench menu. ten we could have MIRRORS in BL. It would have to be much better than the roblox reflectancy.
You do know that this is impossible with the current engine right?
