At first sight sounds like you are not resetting some drawing modes after the
last pass to their normal values. You'll probably also want to multipass only
the polygons likely to need the projected texture applied. This would let you
avoid the fading of lightpoints and all that.
Anything you change in the Pre or Post draw, even if you make a Push/Pop
State, needs to be reset back to it's value. Even the color you paint at has to
be reset to full color and alpha white ( don't ask me why ).
We have tried projected texture with no problems, but I don't have a short
example I can send you.
For that I know, Carl Korobkin wrote the original gl proj tex demo, Michael
Jones and John Rohlf wrote the Performer shadowed Orchidea-hat-stick-chair and
also Javier Castellar has been working on the subject lately.
They should be able to provide you with more help.
