Not sure what your problem is as the instructions on Derek's blog may be old but still work, although the various input fields are in different locations in Max 2016, they are still there.
One small point, I always use an uncompressed texture (-nm suffix) with an alpha channel in the first texture slot, the second slot can have anything you like as it's only an environmental pass.
If you're still stuck please post an image of your max texture entries for us to look at.
