auto smoothing groups

[stevesideas]

Is there a quicker way than using 3dsmax to add smoothing groups to a large amount of objects ? Just auto 45 degree threshold is all I need but max takes forever.

Smooth modifier on all selected objects could do the job in this situation?

That's what I normally do but because of such high poly counts it takes forever. I think because the modifier is only single threaded (can you believe it?!!). I was wondering if there was another app that might be multi threaded that could do the same job quicker. Zbrush doesn't unfortunately.
