As Chowdren presently does not have an exporter for Fusion 2.5 to hide incompatible extensions, actions and events, it is inevitable that without checking the list first, you’ll end up with errors from Chowdren. This is because the particular functionality is missing, and cannot complete the export until it is removed or implemented.

As the project is open source, it is possible to code them yourself, providing you know C++. As an alternate, Mathias offers to port missing functionality on a per-contract basis, as well as hiring him to port your game.

According to the thread, you can officially find out what’s supported at:

  • Implemented Extensions
  • Implemented Events
  • Implenented Objects

This list is unofficial, and is correct as of 13th December 2014.
