It was made by
http://seriouslabs.com/
they used to be called pureLIGHT Technologies but changed name as far as I understand. Also PureLight used to be available for Unreal 3, Unity and Torque 3D on this website:
http://purelighttech.com/
That site is no longer available. However we Torque 3D users are lucky enough to be able to purchase it
It supports collada files
