@ Orrion Carn - Umm, it's been so long that I've forgotten what I was linking to there. I think the linked-to post may have been edited in the meantime. Still, re-texturing tutorials abound, just search the boards.
With regard to the screenshot, Inspire's right, it's a custom wall segment, with an illumination map on the staircase.
@ Corky - I never post my email address on public boards. I'll contact you at the addy you've given here.
@ Deathead - Thanks mate!
@ xplosys - I'm easy to miss, I'm a low-key kind of guy

Glad you like the screenies, feel free to borrow at will.
Cheers
- Graham
