Oh, I'm so sorry, I totally didn't see this notification until now.

That's interesting. The loader only supports some of the object and material features. For example since ThreeDart was mostly designed to run on a browser, if the file contains a reference to another image, the browser has no ability to request the file from the machine that the browser is running on. FBX hasn't been officially supported. Issue 49 has a list of file types which haven't been fully checked nor supported. I'm not sure why the null is being hit in the map.

With the information I have I don't think I'll be able to appropriately address this issue. Also I haven't worked on ThreeDart recently (some other projects have required my focus) but if you have some ideas or fixes, let me know or create a branch for the fix. Any help with this project is welcomed.
