A while ago I announced support for strand-based hair. Over the past month there has been some important improvements. In particular, the hairs now stick to the body mesh without the introduction of a density vertex group, at least in most cases. The topic of this blog post is how the type of children affects the hair.
There are three types of children: None, which means just the hair guides themselves, simple and interpolated. The importer always creates simple children, because interpolated children during load time seem to lead to undesired results, but sometimes it can be a good idea to change the type after the mesh has been loaded into Blender.
