Projector Lights

[Quistess Alpha]

I've seen an in-world effect where a 'projector' prim lights its texture onto the environment, so for example a 'projector' prim with the text "hello world" on its projector face pointing at a wall displays "dlrow olleh" or so onto the wall, if you have advanced lighting on in your viewer. I can't seem to find where this functionality is in LSL, or how to make such a prim.

It's in edit box... in the same place you would set an object to be a light (and where you would set how bright and what color).

You need to have your graphics up high enough to see this option.

LSL has no way to set the texture at the moment.

Oops, I missed the "LSL" part.  Thanks for catching that Wulfie.

Hello, I posted a video on FlickR a few weeks back of me figuring out how  to do a projector while fussing with a light I want to use for taking pictures. This would be just for setting the prim. Not for scripting it. I have a more simple projector now if you want to check it. It's fairly simple.

Like others have said, you set the texture and its associated settings (FOV, focus, ambience) in the edit tool.

The texture and the above settings can't be changed in a script but they survive otherwise altering the light and copying the object, so you can make a projector that turns on and off, changes color, intensity, radius and falloff just like you would do with a normal point light.
