I'm completely new to Houdini, but have had extensive experience with other 3d programs, and I am curious if anyone here has some free tutorials that can get me started with Houdini Apprentice, The interface has got me stumped.
Thanks for your help.

If you search this forum you'll find the same questions asked many times. There are a bunch of links posted by people who have been through exactly what you are. 3D buzz is one that springs to mind.

Someone from Sesi should either pin one of those threads at the top of this forum or post them up under FAQ's.
