Uhh... How could I not think about that? Damn it, it sounds so simple and I haven't been able to understand how it works for a really long time until now.
What's interesting is there's no info at the web how it's done, except TWHL of course.

As always - nice. But can you use smoothing on a certain part of a model or you can only smooth the whole model?
