my apologies on the delayed reply. you can mix the two. the ib3d_engine instance has the fields: device, smgr, driver, guienv, and recv. using these you should be able to mix in any calls to base Irrlicht engine functionality. also, all iB3D objects have fields representing their Irrlicht objects. the MESH type for example has a field called "_mesh" which will give you access to the underlying Irrlicht mesh object.]]>
