Quotes from Octavio Augusto MÃ©ndez SÃ¡nchez:
...The idea is to see if it is possible to use 100% Open Source tools for all the production process, looking to obtain similar results (or superior) than could be obtained with commercial tools...
...the total time of production was 2 weeks from beginning to end, including time to render but without including modeling.
The original model of the fish is not mine, it is from the Virtual Toucan Museum, you can download it here. I made some adjustments to mesh + triangulations and subdivisions to have a better control at the time of doing skining later and with softbody, but in fact they were minimum, the original mesh is very good!
Octavio plans to do new sequence a VFX short with this fish using different lighting and more improvements to the technique. I'm sure we'll all keep an eye out for it.
