I am hoping that this Forum can provide information about the right tools, tutorials and ideas, that can help be to be a better 'mapper'.
That guide is a WIP but it covers basic terrain. If you have questions regarding lighting, blendmap, geometry, proportioning, weapon placements, waypoints, map-commands, ent placement, etc, I can answer in this thread or you can come to Sheeptopia server some time.I'll be making a guide for those too.
Don't worry! No matter how good you are, Suicizer knows better and maps worse!
