One of my ages uses two wavesets in a way similar to Eder Gira. The problem is that the second waveset (which should be lower that the first) appears at the same height as the first waveset. The second waveset's object center is where it should be and the alcscript seems fine, so what's happened?
Are you sure the objects have their own objectname and the Alcscript is refering to the right object? Sounds obvious, but it would be something I would spend hours on before noticing
