Now there are two Hair Systems out for Daz Studio 4.5 ..which one do you use ?
Looka at ma Hair or Girabaldi Express ??
There are several threads on the forums here on both of these plugins. I'm afraid that you will have to do a bit of reading to see which one will suit you best.
Perhaps you should give an idea of what you are trying to accomplish with a hair plugin, and what you are going to use it for? As far as I know, both plugins work in a similar way, and the end results are much the same.
