Phant, I've already gushed about your scene. But it's worth saying again, that is really inspirational.
Until Pat pointed it out I hadn't registered the fat pipes...but I think he has a point
Pat, thanks for art feedback. I'll see what you guys think about the yellow texture when I finally get a full test up and running. The yellow is pretty rusty up close, my idea was to contrast all the grey. I've only used that particular texture for railings, so it would be very easy to change.
The building in the foreground goes down lower than shown here, I think it's more the screen shot than anything. Again, when I get a full art test out I'll take advice
I have one small passage between that area and the rest of the map that needs building, then I'm done.
I'm pretty sure even with all my clip brushes I'm going to have to build a bot only map in order to end up with a playable level, but I really want to get a non-playable test build up to get some feedback.
