"In Dire Need" - Camera Mapping Breakdown


Blender Artist Colin Levy participates in the PSAId contest with an short video. He has also published a video explaining how he made it - focusing on the camera mapping.

"PSAid is a public service announcement (PSA) contest for U.S.-based college and university students. PSAid seeks entries of broadcast and print PSAs which explain the importance of appropriate international disaster relief and build support for international disaster relief work done by well-established, U.S.-based international disaster relief organizations."

Colin writes:

A few weeks ago I made a 30-second PSA for a national contest focused on
disaster relief. Now, it looks like I'm one of only five finalists in the

I just put together a brief overview of the visual effects process involved in
the creation of the short. I used matte paintings and camera projection to
replace the environment in the big reveal shot at the end. It was pretty
challenging, and took me over a week to complete! Of course I used Blender for
everything 3D:

If you'd like more information about camera tracking or camera mapping, I've
got some old tutorials on my site that may still interest you.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. @Bart: Oops, seem to have missed the http:// of the start of the "Colin's website and tutorial" link, also you've used a capital I in PSAid for the link above that...

  2. On a totally different note: That's some decent VFX in that shot... especially for just 2 1/2 weeks. I wish you luck, Colin, for the final.

  3. I don't like voting for something just because Blender is used in it, but after watching all 5 finalists I voted for it simply because I thought it was the best of them all. Great job Colin!

  4. Fantastic work! So you made the transition from Icarus to pftrack I didn't know there was an exporter for blender that really surprises me. did you write the exporter yourself or do the pixel farm have one?

  5. The video as posted makes a wonderful tutorial on camera tracking! Very well done. Bookmarking under video tutiorials NOW! :)

  6. Colin!!! Hey kid. This is the first time I've ever said this: "This entry made with Blender IS the BEST!" and not the first time I've ever said this "You're the man now dog!"
