Hair is a prop, right? VSS by default does not apply to props. You have to go into the "Apply Rules" material and add a Rule to include the hair prop in its calculations. Then you also need to go into the "Shader Rules" and add rule(s) to handle the material zone(s) of the hair prop.

Finally, due to a bug, the hair must be un-parented during synchronization.

I need to get back to work on the VSS user interface so you can skip all those stupid nodes. By re-purposing nodes as rules, I was able to avoid the need for UI, but it's a tedious solution. The Flex/Flash-based user interface I'm building will be much easier.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
