Oldtime master mappers Kinn and Scampie posted screenshots of their work-in-progress maps recently, I added the images and links to http://www.quaddicted.com/pipeline
And during scampie’s ramblings about rotated textures Mr Fribbles joined in and http://www.celephais.net/board/view_thread.php?id=3&start=8207&end=8240. I am not sure why this was not standard all those years. Oh, someone should make a proper zip with a qbsp that does it and then also finish http://www.quaddicted.com/tools/map_compilers
And since I have been name-dropping so hard in this post I must add that czg is my honey.
