So..Adding a new file to your project files folder outside of C2 does not add the file to your project inside C2, nor does updating a file outside of C2 work.
However, if you add the file to your project inside C2, save, close, and re-open..then from then on you can modify it outside of C2 and it'll work.
Why is that? It may seem like a minor inconvenience but it's a pretty big deal if working in a team. Either each member needs a C2 license and the .caproj to add new files in C2, or the one member with the .caproj has to be responsible for adding everyone's project files himself.
Imagine 3 people making hundreds of rooms for a 'vania, each one a separate project file..no way I'm adding/managing all of them myself!
Anyway..That said, could we maybe have a button to add/update project files in a C2 project if changes have been made outside the editor? Better yet, could they just be synced at all times?
