His description is difficult to understand, but it seems like he wants some type
of stencil solution. So the plane rendering pass would be:
1. Render the plane with stencil set to write a 1 bit.
2. Render a fullscreen quad to display the texture, but only where stencil is 1.
Hope that helps? Hard to tell, as the description is pretty obfuscated...

Hello Paul,
Didn't my answer help in any way?
If you want the plane facing the camera see the osgbillboard example. Also
you're giving information in a piecemeal manner. Maybe you could try to explain
what you are trying to achieve.
How do I render the image so it is entire size of monitor, face on.
Only rendering area where plane is displayed?
I cannot parse this. First you say you want to display the entire size of the
monitor, which would be a fullscreen quad.
Then you say only where the plane is displayed, which in this case would be the
full screen. Try to explain so we can help you.
cheers

I need the texture to "always" face the camera regardless of the angle of the
plane, the tuxture being fullscreen and only rendered where the plane is.
