I also tried to revert the wire model of the trench back to blue during the briefing but I did it straight in PD, so I'll have to wait until the next workprint is encoded to see how well it worked.
I did a few more cosmetic changes, like fiddling with the levels to get rid of some garbage mattes and I think I'm nearing completion.
I'll wait a few more days for any other suggestions you guys may present, then I'll render a final workprint, watch it, fix the last few things and I'll be good to encode. So if everything goes well, this should be finished within a fortnight :-)
