Promoting Camera Attr from within vray material builder

[bender83]

Im trying to promote the camera_view parameter of the UVWGenProjection node to the vray material builder level and I am immediately getting errors because it seems vray can't figure out that the result of an operator path is a string... and so it wont accept a string. Is parameter promotion supported, and are the datatype enforcements stuck like?

There is no support for such promotions, this could be implemented though...

aaah ok no worries. I'm not sure it's a dealbreaker at this point but good to know, thanks!

Adding a operator path parameter as a spare parameter to you material builder will work, I never saw a need to add support for parameter nodes to do the same or maybe I just haven't bumped into a situation that it would only be possible with parameter nodes.
