Hi,
as a part of our own shader, we'd like to add a retro-reflective component to it.
(https://en.wikipedia.org/wiki/Retroreflector)
can somebody point me to such a shader in Houdini to start with?
any input welcome!
thanks!

ok, this looks great!
a few questions:
1] does the chosen lighting model (oren nayar) matter much? I suppose you chose if for a ‘clothy/velvety’ look.
2] it seems you ‘add’ the retroreflection on top of the normal reflected light.. do you care if this could result in more light being reflected off the surface than that falls on it (energy in = energy out)?
thanks for the input!
