Any specific places you'ld like to see beveled down a bit? I don't want to rough up every edge, because that'd kill performance and cause clipping nightmares, but I'm happy to damage whatever I need to in order to enhance the feeling.

Does anyone have any specific comments on lighting? I've had very mixed feelings on the lighting of this map since I started working on it, and considering a few major revisions.

I guess I'd have to say, mostly the outside would need "roughing up". Maybe a few jagged edges or holes inside, mostly with the brick architecture. As for lighting.. well my opinion is that its too evenly lit, it could probably benefit from a more gloomy feel with harsh shadows.

Also, have you considered making your boxes not perfectly aligned? The whole level could do with some more randomisation, I get the feeling I'm walking around a box.

I've added a lot of roughing to version 0.8, and you can really tell with the calclight. :( But it does look a lot better. There are a lot stress fractures in various walls, tiles and stones falling out, and some tweaks to the water to make it more rebellious.

Just a note on the water- the concept is that the engineers of this place were planning to have a rotating cooling system for the primary uplift devices that would move the heat over to the other rooms (the Refuge is very high in the air, so its always pretty cold. The plants in the garden have a very hard time because of it, that's why they're so brown despite the world below being pretty green). However, the actual constructors of the place became so attached to seeing the water flow as they were making the rest of the Refuge, that they deliberately left the covering plates off of the channels. Similarly, the engineers wanted almost all of the actual machinery covered up by stone, both as protection and as aesthetically pleasing, but the workers found that some aspects of this plan were just silly (who encases a control panel in stone?), so they left some things exposed.

In regards to lighting: I've done some very minor tweaking to the current scheme, deepening the shadows and such, but I still am considering some major changes. I'm worried that making harder, more defined light will cause perspective problems later (if the skybox rotates around and the sun is opposite where it should be, for example).
