The default parameters ,1.0 and 1.0, I believe work fine in most cases. You’ll have to experiment to determine what parameter values work best for your app.
Which is slightly different from what I explained in my previous post (i.e. I use polygon offset on the filled objects and not on the wireframe ones…).
I remember reading that you can get z-fighting between the solid/wireframe if you do not carefully choose the polygon offset parameters…
Don’t know more about it, sorry…

P.S.: if you search the forums for polygon offset, you’ll certainly find more.
