I came on Priest while it was in distress. There were lots of issues with the shots and we were right up against deadline. Initially, I comped a couple shots in Nuke, such as the shot of Priest crashing on the top of the train, after taking a flying kick to the chest (that part wasn’t mine), and of Warrior setting up TNT on the train tracks. However, what should have been simple set and prop extensions had many technical issues on the lighting and rendering side, as well as tracking. The windmill shots, for instance, may seem straightforward, but I can assure you that they were the most expensive cg windmills in the history of film making.  I went to the 3D side, and did a fair amount of troubleshooting, from optimizing geometry, scenes, shaders, relighting, render setup… The camera moves were so subtle that fine geometry was creating aliased artifacts. There was a lot of re-rendering involved.  This was done at Gradient Effects… Maybe they’ll want to hire me again for being such a handy guy!
