When I watched the SourceTV Demo of the last Gameday on my map (htf_sebi_a4) today, I heard players agreeing that it has an obvious "First-Map"-ish layout and feel. While that is true and I can perfectly accept that, I asked myself how does it come that players feel this way? How do the more experienced mappers plan and layout their maps? And how do they convert them from paper to vmf? I always hear about height variation as one of THE key elements that can make a map truly great. Agreeing to this, I ask myself how to plan proper height variation. My piece of paper is 2D after all. Planning How do you do it? How do you get past this most important of all parts of creating a map?
