A SI user called Tom Kleinenberg (thanks Tom) showed me a great ICE tutorial by Mark Schoennagel in which several ICE strategies were used, and after contacting Mark himself, I decided to adapt those very same workflows to Houdini, as directly as I could.
The idea was to try to show both approaches to problems. On one side, a typical Houdini approach, and on the other side a direct translation of the ICE technique to Houdini where possible.
Please, if you are rather new to Houdini, your first step should be reading Jordi Bares "Softimage to Houdini guides
Then, check this IntroVOPsForSIUsers scene I shared a few days ago (attached below)
And then go for the tutorial.
As it is pretty long, I add here a summary of the contents so you can decide whether it´s worth your attention or not.http://vimeo.com/89869747
Just a little disclamer. I had to record this pretty late at home, and because it´s so long, I didn´t have the time to re-record and fix all my “humm..”s, “aaaah”s and “eeeh..”s. I appologize in advance for that. I hope you still find it useful.
