I dont know if you can ghost sprites in DB, (I think this should be in the 2D forum), but my 3D suggestion would be to map the image onto a plain and ghost the plain

no it's not possible to do this with one command

you could write a function to do this manyally by mixing color values that you capture of every pixel (once with the background and once with the sprite visible)

i you understand this (my english isn't very good today)

The easiest thing to do is to "Stipple Alpha" the image. This is done by making every other dot on the image Black an will give some sort of transparency. Alhough this is a extremly cheap way of doing it. you should be able to see the image underneath it.

you could make it a textured plain object a few away from the camera with a ghost on the plain..
