I decided to do a little reworking of the Mausoleum model found in the Poser Library as an included content.  I created new interior groups using the Grouping Tool and performed a number retexturing using AI generated images.  I even dusted off the old Ivy Generator and dressed the old structure as an abandoned tomb.  Using a combination of a modified HDRI and one infinite light with Blackbody moonlight and PostFX applied, this is what I came up with.

The intense shadows is intentional to give it an eerie environment.
