Can any of the lights take an image map to make a gobo?

I'd like to use a gobo every now and then. I recall—vaguely—that an early version of DS had the capacity to put an image map onto a light to cast leafy (or whatever else) shadows. It's a nice, low-render-cost trick I'd like to use, but I don't see any way to do it.

Advanced Spotlight from AoA can, I think there are others but cant come up with any right now, all I know none of the built in can.

Uber Spot and Points can too. You could always load a plane, parent it to the light and load in a trans map to the plane as use that as a Gobo.

OK, since I'd missed that what I was already saying had been said I wil isntead add that if you sue a mapped primitive as a gobo by placing it in front of a light source, remember that for a coloured image you need to invert it.

Thanks everyone. I'd had some bad luck layering planes with transparency in the background, I'd shied away from that kind of effect. But one pane parented to the light should work wonderfully. And knowing to invert colors is great for leaves and the like

Yep. :D That is what Easy Shadows does in its entirety. It works perfectly fine, although if I were recreating the product now I would put Ubersurface on all the planes to make them go faster.
