unwrapping tutorials

Hello all you creative geniuses!

I've been using cinema 4D at work for a little over a month now, and I have to say I'm absolutely loving it. This program is just fantastic.

The one thing I'm still struggling a bit with though is unwrapping. I've done a bit of searching to try and find a good unwrapping tutorial, but all the ones I've managed to find seem to either assume you already know the entire unwrapping interface, or they just show you how to apply a standard cubic a box.

Can anyone here point me in the direction of a few good unwrapping tutorials that walk you through how the interface works? I used to be pretty good at pelt mapping and the like in 3ds max, but I just can't seem to make heads or tails of the body paint interface in C4D.

Thanks for your help guys!
