Quote - Great job on the wrap! I've been having problems just adding a new shader to dynamic hair - I get the pinwheel every time. Any ideas?

Sorry, don't know what you mean with getting the pinwheel all the time. What are you trying to do? I use the standard shader and change some settings with no problems at all.
If you want to change the color you can click on the color and you will get the pinwheel for coarse selections or you can click on the little arrow to get numerical entry for exact color selection (as always in color selection in C5 or C6).
Using a texture map in density or length can create some interesting effects (begin with a ball and some big contrast texture map to see the effects).
The last 4 parts of the shader should be used with care, they quickly go over dramatic, a little bit goes a long way. Note that any change in the shader will require rerunning drape and simulation to apply the changes correctly and might upset any careful brushing, always try one thing at a time and build up slowly.
Remember anything that works on short hair might not work well on longer hair.
