I'm gonna have to look at this map now.

Every map I have has been stripped down at least once, though not always in great detail. So I can't specify anything in particlar. Personally I have only really mapped properly for blood/sw until recently, so I learned most of the sector/spritework tricks from that or trial and error. I remember figuring out sloped shading myself, but I learned the SOS trick after spending hours looking at what I thought was a corrupt E1M1 in blood and Lunatic Fringe in Duke 3D.

The map I poked about the most recently was probably "Blown Fuses" by Gambini, mostly just to see how DukePlus worked and to look at the spritework in detail.

One thing I have been trying to figure out for years is how those multi-story elevators work in LameDuke - though I don't think that qualifies for this thread.
