problem with normals on 3ds files from blender

[pera]

I export blender model to 3ds, and when I load it to irrlicht each vertex has three normals instead of one, so lighting is not smooth on these models but broken on edges so triangles are visible. anyone knows how to fix this?

Export the models in OBJ format. 3DS doesn't have smoothing groups, because Irrlicht doesn't load them.

Other thing would be to use the mesh manipulator, and weld the vertices, maybe that also averages the normals, and gives you a smooth model. (not tested, so i can't tell for sure)
