collada export

i tried to export model with uv maps and animation to collada (1.4). it works good, animation works, uv works, model is ok. but I also need to have smooth geometry. Smooth works ok in blender (i just turned on set smooth). but collada export looks like I turned set solid. And I need this export smoothed. Is it possible?
Another format I can use i VRML, but it works much worse than this collada. it is without texture, non smoothed and also animation doesnt work.
thanks for any help
