I'm slowly but surly learning how to use newtons with irrlicht. I have succeeded in having objects colliding with each other. However I am having trouble with the collision tree part of it. I want to be able to load a level and use the collision tree to make object react with it. The tutorial 3 that talks about tree collision but it just confused me with the
collision = NewtonCreateTreeCollision(nWorld, LevelCollisionCallback);
how you can set LevelCollisionCallback to NULL and add triangle face youself. but i am lost with that. So can someone show me how to load a level with a file format .x or .3ds and use the collision tree so object will react and bounce off (not go through it) the level. Thanks in advance.
