This is my remake of Roughinery. 90% faithful geometry, a bit warped vertically to allow for efficient cube placement. 80% faithful on pickup and spawn placement, matches the original as closely as possible, although substitutions have been made. Light placement is 90% faithful, although lighting is much more intense than the original, with brighter bright areas and far lower ambient light, making for some pretty dark shadows.
The map has been saved with lightprecision=128 to keep the size down. To see some of the beautiful lighting that Sauer is capable of I suggest doing the following:
/aalights 2
/lightprecision 8
/calclight
