Select Random Strands

Another way to speed up hair creation is to reduce the number of strands of the mesh hair that we started from. This tool makes this easy. With the hair mesh selected, press Select Random Strands. A pop-up dialog appears where you can specify the fraction of strands to keep.

Strands are selected at random in edit mode. Now we can easily delete all selected vertices. This leaves Aiko with hair that is thinner but closely resembles the original hair. We may be able to make up for the missing strands by increasing the number of children in the particle hair.
