Wings can set hard edges and poser can read those when the object has smooth OFF

What I wonder as a modeller is : what should I do on wings so that my model takes advantage of poser smoothing for a result of lower resolution mesh and still render hard edges right. Not for this model but generally, is there a modelling technique?

Here is the same model, I selected the hard edges, than bevel, than tesselate the whole model - Quadrangulate (this way Wings tries to create 4 sided polygons and if not possible triangles) final model is illustrated on first image imported in poser

than set crease angle lower at 45 and got the ballon effect

The UV mapping is done in UV mapper and the texturing will be done with photoshop
