So you've got a map. You're ready to compile. But what do you need to do before you compile to make sure nothing is broken? Here's a handy list of things to doublecheck: Spawnrooms Are there 16 spawn point per spawnroom per team? Is there a func_respawnroom in the entire spawn area? Are there any resupply cabinets? Is there a func_respawnroomvisualizer for each door for each spawn? Gametype Entities Are the entities you need for the gamemode placed and set up properly? Lights Are there light entities inside of buildings? Is there a light_environment for outdoor lighting? Cubemaps Do you have cubemaps placed 64 units above the ground? You should have more than one. Sealed Turn off all visgroups except for World Geometry, and then turn off displacements and water. Do you have any leaks, or areas that stare into the void? Optimization Have you func_detailed stairs and other brushes that stick out? Have you added hints and areaportals where needed? Did you nodraw unseen faces? All Visgroups Checked Are all visgroups checked off? Now you've compiled. You're anxious to test, but we wouldn't want to test a broken map. Let's doublecheck and make sure everything compiled correctly, and you didn't make a mistake. Compile Log Errors Are there any errors in the compile log? Head on over to Interlopers and paste your compile log into their Error Report. Spawnrooms Do both teams spawn in their respective spawnrooms? Can they leave their spawn? Are they not allowed into the other teams' spawn? Does the resupply locker work? Gamemode Can you cap each point (cp)? Can you pick up and capture each flag (ctf)? Does the point unlock when it's supposed to (arena, koth)? Lights Is the map lit and not fullbright? Clipping Are all places clipped properly? Don't worry about "clipping with a fine tooth comb" for an alpha. But don't let me out of your map, either. Cubemaps Did you build your cubemaps? From the main menu, open console and type the following: 'mat_specular 0' then 'map <yourmap>' Once it loads, 'buildcubemaps' and then 'disconnect' Then 'mat_specular 1' Packed Did you pack any and all custom material into your map? If you answered 'Yes!' to all of those, you're ready to test! If not, go fix 'em and try again. And remember not to rename the .bsp manually after you compile or build cubemaps! Always rename your .bsp by compiling it as a new name in Hammer. If people are harsh to you for having big errors in your map, just know that if you fix it next time, and truly fix it, they'll give you some good feedback. But don't be mad if we skip the test due to errors.
