Continuing the discussion from Welcome to Script libraries & Overlays!:
I hear you - I was working with the FBX SDK not too long ago at another job, and the stuff would frequently crash deep in its binary guts, and it was a pain contacting Autodesk support and getting to the bottom of it, not to speak of long-winding internal legal procedures to approve sending over the slightest snippet of our source as a test case to Autodesk. It easily took more than two weeks before an issue was resolved. Luckily nobody heavily depended on that system yet at that time.
That’s one of the reasons why we made the source for AgogCore available (and the UE4 integration of course) and put everything up on GitHub. The SkookumScript runtime is still our holy grail so to speak but we do definitely consider eventually open sourcing it as well. But let’s see how things actually go on those other platforms first.
