[Kaimetsu]

In principle it's already possible (if I understood Stefan correctly). You'd just need to hardcode all the positional information for the sword at every stage of its movement, so that the gani knows where to put the lights.

Oh, and the image layers might cause problems too. Because, as far as I've seen, any showimgs within a gani's script are treated as separate entities and not part of the character itself. Hopefully all this stuff will be resolvable in time (I'd personally like to see some method by which a showimg can be masked, such that the light would be cropped to the shape of the sword).
