I would like to know how to view a GUI on one face of a brick, but I'm not sure how to do so.
Any help? It would be much appreciated!
Simply use a SurfaceGui
To make the GUI simply select the brick, add the SurfaceGui, from there add a Frame, then change what side you want it to be on, using the SurfaceGui's properties. From there you can design your GUI. If this is not what you are asking for, please comment on what else you want to know!
