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
If you read about the product on the GG site:http://www.garagegames.com/products/purelight

I bought it and I really like it
