I compiled my map and ran it. When i join the marine team or run in spectate everything runs great but when i switch to opfor i get a big red blotch in the middle of my screen and see nothing but red. On the outer edge of the red i see the map but in the middle theres like two big red triangles or squares i dont know why. if i use the sniper rifle they are there but when i scope up they disappear.

If you was to zoom out that big red thing is actually a 'fx' model, you need to update your zonefiles for opfor.

i updated the zonefolder but it still does it i will try again

If you are running your map from a Mod folder, i.e., Mods\ModWarfare, look for the "missingasset.csv" in there. Copy "missingasset.csv" from the Mod folder into the game root "main" folder. Try that out.

From the IW wiki:

Each time the level is ran and tries to load an asset that wasn’t found in the fast file an output file called missingassets.csv is created at [root]\main\missingassets.csv. This file contains a list of assets that the game tried to load but couldn’t (due to them not being stored in the fast file that was used). If missingassets.csv is not being generated then your level fast file and zone source are either up to date with all assets, or you may need to try running the level using the “developer” and “developer_script” option turned on ( found under the “5. Run Selected Map” button ).

These missing assets need to be added to the [levelname].csv zone file so that they get included next time you build the fast file. This is as simple as copying the asset list from missingassets.csv and pasting them at the bottom of the [levelname].csv zone source file, however CoD4 Compile Tools can make this easier for you.

When you click “4. Update Zone File” a new window opens showing the contents of both missingassets.csv and [levelname].csv and allows you to easily move over the assets you want and save the new file.

Add these to your zone file:

include,mptypes_desert
include,mptypes_woodland
include,mptypes_urban

Or only the one you use in your map. Then update the zone file.
