I don't work for Refractive anymore. I'm currently working on a little private fun project, but might continue working on LuxC4D again some time in the not too distant future, if there is enough people who would like to see it updated. Of course, if someone else wants to take over, the source is available in the LuxRender repository. Just help yourself
I would help as much as I can during the transition period. Or a coorporation with another plugin dev would be fun, too.
