Blender export 3ds with smooth

Hello,
I am new in Blender so I make some basic testing.
No I have made a test model and want to export it to Holomatix Blaze 3D Studio which can import these formats - 3ds, lwo and lws (also from 3Ds Max and Maya scenes, but I don’t use these softwares).
Problem is that I didn’t find a way how to export my model with Smooth - when export using 3ds, model is imported without Smooth, also with another file formats.
So is there any way how to transfer Smooth to another application directly from Blender? Or do I have to use for example GMax, import model, set Smooth again and re-export?

Thank you for help!
