I've been keeping myself overly burdened and busy with the re-doing of the tunnel from my previous demo reel. This time around, I actually know what to do so I've been attempting to do it correctly.
The tunnel, even just for this shot, had to be broken into 8 pieces so that I could properly UV and texture them. There are still a few things that need tweaking and obviously theres alot of detail missing from the shots (beams, clutter, tools, rocks etc) but I found that the end result of the tunnel so far already looks far better than the old tunnel. I've also been playing around with depth of field. We'll see if I keep it though.
