I had some requests to put something out on how to set up multi projections in Nuke. A late Christmas present--I hope you enjoy it.
For more info, watch the shot breakdown, download the working files, all from the article I posted:
Basic Nuke Multi Projection Setup for Matte Painting
Do me a favor and post something under the article on my site. That is really the only way I get feedback on whether or not people feel these matte painting posts are valuable.
