Hi there,
I’m a 3D artist who has been using max for FX for several years now in TVC work and film.
I’m starting to learn Houdini and I was wondering if anybody could recommend any books that can assist me in learning it more quickly? I’ve been looking at online training videos, but would also like some book reading material, so that I can still learn while not required to be in front of the computer screen all the time. 
Thanks!
Steve
