So basically there are 2 options. 2D and 3D.
When 2D is selected, the brickTOP textures will just be the flat texture, nothing more. Just like we have now.
But when 3D is enabled, the textures will be replaced with 3D studs, in the same design. I think it would look awesome, and wouldn't be that hard to make.
Unfortunately this might not be possible with Add-Ons, so Badspot will need to do it.
For those saying "but it would be too many quads, my computer couldn't handle it!", just keep it off.
