Pret-a-3D:  If I install Luxrender ,the one that installs its self  ,will I have a problem when it installs if my runtime is on an external hard drive ? I mean does it need to install in the Poser program on my system hard drive to work ? Or will it work if its installed on my external hard drive with the runtime? Will Reality 3 work with the same situations as  above ?

Thanks .
