Model gets smoothing wthether I want it or not!

I have a tank and I have set up my smoothing groups on it.
The Turret does not have smoothing, but the exported model is always fully smoothed regardless of whether the 'Smooth normals across meshes' is disabled or not.

Any ideas if it is possible to prevent this auto smoothing?

The compiler interprets all surfaces without a smoothing group as having the same smoothing group. If you wish to have an unsmoothed surface you have to make sure that all adjacent surfaces have different smoothing groups from each other.
If that's too much work you could try using the Auto-Smooth function with a very low angle setting. This'd only work if the surfaces were actually slightly curved towards each other.

Generally you shouldn't do this though. Unsmoothed surfaces are created by breaking apart the edge vertexess o you can easily quadruple your vertex count this way.

OK thanks for the information.

I'll have to manually set up the smoothing groups on the turret then.
