It's a 3D 'studs' effect which seems to be automatically added to bricks. Ignoring the "Lego" rounded effect, would it be possible to add this effect to the engine for Blockland-style studs? Such an effect could be enabled or disabled in the Options menu, perhaps (as the Brick Physics will be), with it displaying as it does now if turned off. It might make some builds look a lot better. They probably wouldn't have collision or affect gameplay in any way - the Lego figure there just clips through them. (at its feet)
