actually the blender route is not said to be reliable. something about the collada in blender not being perfect.

 

I can attest to Khai's method, or you can yell at SM for thinking Collada is a pro feature which it's not or the google team thinking OBJ is a Pro feature. but other than methods such as the one given, you are looking at Rubies that, while we're glad of them, are unreliable.
