I am making a pretty big cave map thats completely underground and I've made 2/3 of the spawns. This is my first map and I'm used to dealing with 3d modeling software because I spend alot of time working in blender. Anyhow I have a few questions. I have modeled the first 3rd of the map in cube shapes and then I will apply displace and make them into a cave etc. My problem is that when I tried to do that on the portion I've made so far, it kinda got screwed up. I managed to fix it by destroying the displacements. Does anyone have any tips for making large caves? Also I was having trouble sewing faces together (yes they were both the same number of displacement). Btw the map is a payload and I have no damn clue how to make the payload triggers or whatever. Also I've made the map all on graph paper before hand. Another question would be how to make one spawn switch teams mid game when the cart caps a certain point. Sorry if I posted this incorrectly but I'm just getting used to the site and also to hammer.
