Why won't Radiant let me edit any verticies on a terrain patch or on curves?
Once you have the verts selected you need to make sure you hold the ALT and Left Mouse Button together while you click move the mouse. You cannot move the verts by only using the mouse.
I compiled my level and everything has a red tint. Why is it doing this?
Anything with a red tint indicates that it doesn't have reflection data. If your entire level is tinted red that means that you probably have not compiled the reflections for the level, or that you didn't have any reflection probes in the level when you tried to compile the reflections.
Reflection probes are very important for the look of all shiny things in the game. Place one per room and one in each distinct outdoor area and additional ones near any especially shiny objects. They use memory but its reasonable to have 10-100 of them.
After the BSP and Lighting have been compiled you will want to compile the reflections for the level. In order for reflections to be compiled properly the level needs to contain reflection probe entities throughout the map. Each reflection probe in the level will produce a cube map for that area during the reflection compile. The reflections used throughout the compiled level use the cube map from the nearest reflection probe entity so keep this in mind when you are placing the probes. The reflection probes use portals to determine which is the closest probe so you don’t usually need to worry about an inside probe affecting an outside model through the wall.
After you have compiled the lighting on your level be sure you have reflection probes placed throughout the level, then use CoD4CompileTools to compile reflections. Now your level should look good, and you should no longer have anything showing up as red.
I compiled my level and all of the models have a rainbow tint. Why is it doing this?
Rainbow models mean there is no grid data for them. You need to define the grid area for your level. More information on fixing this problem is located on the following page.
When selecting "Run Selected Map" from CoD4CompileTools on a multiplayer map, it loads the custom map but then goes to a different map. Why?
You are probably getting an error on your custom map but aren't seeing it. Before clicking "Run Selected Map" make sure you have "developer" and "developer_script" checked so that you'll see any error. If you run the game without developer and developer_script all errors will be hidden so you wont see what's wrong. It's always a good idea to turn these on when you think you may be having an error.
One of the possible causes for this problem is that you have omitted Spawn Entities in your map. Check this link for more informations on creating Spawn Entities: MP Mapping
I have a huge red FX model stuck on my face when I loaded my custom level, what's that all about?
This is caused by your zone_source csv file to be out of date. The game is trying to load an asset but it can't because the asset it's looking for was not in the zone_source\[levelname].csv file, therefore not getting compiled into the fast file. See the "Update Zone File" category on the Compile Tools page for more information on how to update your zone file with new assets. It's likely that anytime you place a new character into the game you'll need to update the zone_source.
