I have seen a request or 2 about this but don't see any plans on the roadmap for it. I'm sure I am not alone in wishing for an OSL shader that will allow us to easily add window interiors etc. I understand Redshift and Octane currently have this. I have looked for a workaround but unable to get anything working at the moment. If someone knows how to get it working please let me know.
Thanks,
Phil
