Clipping a series of sprites to a rectangular area

[GreenflyStudios]

Hi all,

Help would be greatly appreciated with this. I have the following (rough) window with a series of sprites running through at the bottom (the train):


What I would like to do is clip the train so that it only appears within the red outlined window. Anything outside of this window is rendered transparent. Is this possible to do? I've looked around and the clipping only seems to apply to a singular sprite, not a series of them nor a rectangular mask of the window/contents.

Any help is greatly appreciated!

Look at the tk2d UI clipping examples. The UIMask will work fine there (as long as it uses the normal ui shaders).
