[Closed] environmentMap file question

This is probably a really dumb question but here goes. I’m trying to capture image name and path from environmentMap’ but can’t get past getting map slot instead ex.‘Map #3:Bitmap’. Don’t use scripting for matieral editor much so kinda confused on this one.

Have tried ‘backgroundImageFileName’’ as well but just getting “” back instead.

There’s a simple obvious solution to this but not seeing it.
