In part 2 we witness a live editing session, so you can see how long it takes to get a reasonable walk loop up together. (It's about 20 minutes when you are in practice).

Essentially the technique of set up a basic z height map for the stairs to be walked up, then move the feet to fit.

Actually doing this takes a bit of practice though! However I do hope you'll stick with the tutorial because at the end I show the final sequence which if I hadn't got you to focus on the feet movement (so it was being watched for the first time), does the job.
