I found Max very difficult to use as I am so used to the Maya Interface and the way it works. Max works in a different way to Maya. Maya users nodes, build up on one another and Max does not.

Max is a great app, but I think your biggest struggle will be with the UI and certain things not being available in either Maya or Max.

Good Luck. I am sure you'll get the hang of it. I have looked for the guides, but am having no luck...
