I have a model that is being split in a few parts which get assigned different materials and string detail atrribs.
When I render I need to be able to embed metadata into the files. I have no idea where to start, is that a post-script function? So I'd like to have metadata along the lines of "Model=1 - Part=1 - Material=wood", things like that. I don't really know where to start with that. Any help would be greatly appreciated.

I am rendering with Redshift if that makes a difference
