Here's a 2nd tutorial, slightly longer than the first, which explores creating a slightly more complex hairstyle and goes deeper into the use of the hair room tools and hair shaders to demonstrate making a hairstyle which has volume (curls, waves, etc) and also retains it's shape while still giving quick animations for realistic movement.  Here's the teaser animation of the style developed:

This tutorial follows along from the first tutorial, which is for a more basic hairstyle, and if you missed that one I recommend watching it first.  You can find it here:

And an animation example of the hairstyle developed in the first tutorial is here:

The goal is by the end of the two tutorials anyone can have a comfort level and understanding of pretty much all the tools in the hair modeling and shader rooms, and can quickly and easily put together nearly any hairstyle you like, which will also render extremely quickly.  This 2nd tutorial is longer than the first by a little bit, but in actual practice you should be able to create this hair from scratch in about 8 to 10 minutes, and render time probably not much more than that too (it's not all that complex or precise).  I apologize if I drone on in the vids, I wanted to make sure I was taking enough time to give full explanations as I went.

I am thinking of doing one last tutorial for an even more complex hairstyle, but if I do it will be a pretty short tutorial since I've really covered all the tools and most of the approaches in these first 2 sections, and there won't be nearly as much need to stop and give explanations  :)  I'm really enjoying playing with Carrara hair.

Also hopefully soon I'll be able to start posting a few hairstyles for free use of the community, hopefully for use on any figure/character (got to test and get the kinks out first, to make sure they can be used with any figure without problems).
