Why not try the torque engine [smile].

Unless you are willing to spend the time integrating it yourself, probably not. Ogre is an amazing (commercial-quality) rendering engine, but in my experience it does not integrate well with existing solutions (unless you do manual code surgery (aah, sp?) ).

Doesn't Irrlicht come with its own graphics engine? If that's not enough, then you will have to change the code yourself or get a new engine. Torque is nice, but is very FPS-oriented. It also costs money (albeit not a lot...), which I don't have.

Hope it helps!
