I have made some stud bricks to see how they'd look in-game. The problem is that it wouldn't be possible due to the way bricks are rendered. To begin with, the brick looks terrible with the studs because the side textures don't continue on top and wether I don't put textures on the stud, or put side textures, they look bad and stand out badly. Additionally there are problems on how does the shaders render the shadows from the studs, the shadows rendered on studs by studs is just bad given the small area.
It wouldn't necessarily be hard to implement for someone like Port or MARBLE (bannedanyway), and not to speak about the lag, as it can vary on the build, but the only reason you'd think the bricks look better with studs is because you think there are no side textures, or that no one uses shaders (because they do look better with no shaders though) like I have made it in that picture. However that's a Far Cry from the truth.
