*Allan McKay. I started following Allan McKay a few months ago & he's got a really great program with super good content.  He's very experienced on major motion pictures we've all seen, & he does talks about working on top projects with leading industry professionals. He's also got a lot of these Pro's in his Podcast. Recently I've been catching his Live Videos on Facebook, sharing real insider info & techniques from some of the worlds most accomplished VFX artist.  I cant really pick what/where to link to because its all so good, so I suggest you hunt around, dig in to his older stuff, & FOLLOW him on Facebook so you can catch his new Live Videos. (His main focus is ?MAYA/3Ds Max/Houdini/Fume?) Don't get hung up on what software it is, & tune in for the 'Industry Insider' real talk, with him & his talented guest speakers. This stuff is VFX Artist 'Gold' for Movies, Gaming & 3D enthusiast.
