This is the ($$) ''Old Bunker for DAZ and Poser'' by evg3dren which I found over on Rendo.
Not free so no link.
Poser version cleanly loaded its ~37 MB OBJ and many nice textures into P_11. I turned up the emissivity of well-labelled ceiling and wall lights. In ''preview'', there''s an odd patch on floor by 45ยบ angle into side bay, perhaps a machine stood there.
I loaded Rendo''s LaF + Combats. Had to set wide-screen and 10mm focal to do justice to scene. My twin but ageing GPU cards ''fell over'' due complexity. They do. A 14-pixel CPU-only render trial was okay, so I sent job as 96-pixel Superfly / Progressive to my network render ''Box''.
The floor texture oddity did not render. The set lights were not as bright as I''d hoped, I''ll try to re-do with ''nodes''. But, ''Ominously Ominous'', yes ??
