You can also sort of simulate it by just subtracting the height you want from the NPCs Y and then customly drawing the shadow at it's actual location, though it'd normally still block at the new space you put it, and the 3d terrain likes messing that up.
Another easier way would just making a new gani, though that'd still be a pain since I believe variable sprite locations per frame still aren't possible.

Anyway the subtracting from y trick does work for showimg, which is quite handy.
