Ok.. I've decided after giving tons of feedback on other mapper's maps to slowly start work on my own. I made a couple Quake 2 maps back in the day and I've modified a few TF2 maps (very minor changes), but this will really be my first map. The theme is going to be pirates vs ninjas (pirates will loot the ninja's shrine) and will be loosely based on the community map my clan had started but got nowhere on (http://forums.yinyarr.com/viewtopic.php?f=15&t=448). I put about 45 minutes in today and made a little progress blocking out the first section, but I've already run into my first problem that I hope someone can help me with. This first picture is what my ground looks like in Hammer: As you can see, I've lined up the vertices of each block so it looks like one big surface. This is what it looks like compiled: As you can see, the edges aren't lining up. I will be using displacements as well in certain areas, but I wanted to get the overall structure together first. This is a beach, so it's quite complex... it wraps around the harbor area and slopes to the water from all sides. Any advice someone can give will be greatly appreciated.
