I'd love to be able to get animated prey. They would be fun to have & make. However, it would need to be programmed in, as Thierry said, which won't be possible unless KovuLKD programs it in.
In any case, I probably wouldn't make it a just animals thing, I'd probably request that an option be added to object maker, that allows for actions to be preformed that were exported along with the .mesh file. It would allow for multiple effects on objects too then.
But anyway, yes, want.
But not sure if we'll have it.
