The Collision detection example has a scene node picker, which uses bounding boxes, how would you implement a scene node picker which is more accurate. It would be very poor if I used a bounding box to test what a bullet hit.

You could scale the models for the players height and weight, and change the textures for different skin etc. Not sure about changing the actual model though.

I thought it was just cout, rather than wcout. What are you trying to do?

You can use md2, x, 3ds, most things. Apparently blender is good, the gui takes a bit of learning though. Most 3d editors would export to a supported format.

Specifically the bit which positions the billboard, you would alter that to reposition the camera. I'm not sure about the camera rotation though.

The sample 07-collision may be helpful.
