Doesn't matter, polygon modelling tutorials can be easy applied to any software.
I've seen some of them, and though I am a Max person myself some of those can come in really handy like ear modelling, foot modelling, and just about anything organic.
I looking for any tool for import scenes from Maya into Hammer? Not props, coz. Such things work well in S.T.A.L.K.E.R. SDK! Maybe it looks silly, but anyway...
