Hello guys,
I have problem with the radiant ! When I create a map I can't launch her !
Error : Could not load level fastfile for level 'zm_map': Could not read fastfile.
I have try to upload the map on the workshop and its dont work too !
Need help ! 

That's an easy one.
You haven't built the main files using the launcher...and if you did, somethings missing now.

Backup whatever you've made, go to the launcher (the BO3 MOD TOOLS ICON), go to file > new and click "new map".

Type whatever name the map is going to be mp_mapname for a multiplayer map or zm_mapname for a zombie map.

You will see that a popup appears saying it's made a heap of files.

Copy your map into the map_source directory and overwrite the one you just created with the launcher.

Providing all the models are working, the map should compile fine.
Hope this helps

You also need to compile you're map every time you change something in radiant, in the tools you check, compile/lighting/link and hit build

I have compile my map : with Compile Full | Medium Light | Link | Run and i have write the name of my map.
After this I have upload her on the Workshop, download and she not working again ! 

Sorry for double post but :
I have retry to recompile with : compile, light and link.
And when I to run after the compile I have an error :

Error during initialization:
attempting to PMem_Free 'PerLocalClient' but it is not at the top of the stack

Thanks ! 

I have the same error, any solution?
