hmm... i gues you have room and two chairs as one mesh. if so - you cant move or rotate them. If you want to control objects then create separate nodes, use separate meshes. to move node use node->setPosition() or node->setPos() (dont remember), to rotate - node->setRotation()
hmm... ok.. other example..
In 3dmax I create car, one mesh is the body and another 4 meshes is the wheels... Exporting... and now is the problem... How can I turn only the wheels and not all car?
What Roxas is saying is Irrlicht will treat all your objects as one mesh.
You need to export a wheel and the car separately. Load the car and make a Node with it. Load the wheel and make four wheel Nodes as children to the car Node. Then you can go crazy with all the rotation you like.
Yes; once you've done that the wheels position will always be relative to the car; that way you wont' have to move the wheels each time you move the car.
The .irr format and the collada loader do support scene loading. The an8 loader from Sudi also does. There is no really clean interface to scene loading (IMHO it's clumsy do to mising access features), yet, but it is possible. 3DS does not support scenes, though, as do many other formats.
