ive created a terrain and a scene node. ive set up the triangle selector. ive set up an event receiver to move the node.
when i move the node around the terrain it slides up the mountains but when i move away from the hills it doesnt fall down unless i release the movement key. when i release the key it falls down as it should... but why doesnt it fall down in the first place???
Scene node collision with terrain
