[Mono-ue] Anyone had any success with anything except Play In Editor?

Thu Jan 8 22:40:35 UTC 2015

The /Script/... is not a real folder, it's an internal "path" under
which the exported C# classes are registered.

If the Mono plugin fails to register the classes for some reason then
UE would be unable to resolve references to them resulting in error
messages like this. Are there any LogMono errors in the log?
