Fbx open source converter

I'm sorry, I should have mentioned this, - I use a mac. All of autodesk stuff is hostile to the Mac platform, like it doesn't even exist. Is there an FBX converter for sketchup, nonpro edition that can be used on the mac?

Free SketchUp can export to COLLADA format, which unity can read. Try exporting your model to COLLADA.

I believe Non-Pro google sketchup doesnt allow exporting in many if any types that are really usable...

Come on, autodesk products cost 4-5k, sure you can afford sketchup.
