Generate quick interview backgrounds with Archimesh for Blender

Here’s a puzzle:

You’re working on a science documentary where all but one of the interviews were shot on green screen — in different locations, with different lighting setups, different cameras/lenses with different operators. Some of them are over or underexposed and the blown out or crushed areas of the footage are unrecoverable. No background plates were shot, and none of the stock imagery you have to work with matches the lighting or camera angles. Quick, make the interviews look like they’re in ten different locations yet belong in the same film. 

Solution: throw together a couple of CG “science” “labs”, and make ’em super blurry so no one can see how simple the geometry is.


(Note: these, and all the images in this post, are raw test outputs. The films haven’t been onlined or color corrected yet.)

I didn’t have a lot of time on this, but Antonio Vazquez’s Archimesh add-on for Blender makes it possible to build interiors very, very quickly.  Blender is definitely not my favorite 3D application, but there’s nothing like this add-on available for C4D. And Archimesh is free!

1. Enable three Blender add-ons: Archimesh, IvyGen and Sapling. Fake up some lab/office interiors with Archimesh (some great how-to videos here), then add some plants with the other tools. (Gotta have plants. It’s a documentary about plants, and these folks are pretty much all plant scientists. )


2. Export the geometry to C4D. Play with the materials, match camera angles and lighting to interviewees, then render out of focus. I only built a couple rooms for ten interviewees, just moved the camera around and changed the colors. It would be pretty trivial to adapt this setup for multicam interviews.



3. Composite and tweak color in AE. compositetest

As long as your final result is this blurry, your ivy can just be a bunch of square planes, and no one will ever know.
