How to create "texture projector effect"?

Is it possible to create "texture projector effect" for TGEA interior like www.ozone3d.net/tutorials/glsl_texturing_p08.php ?



Actually i am trying to use LightMaskCubeMap ...
------------------------------------------------------
datablock sgLightObjectData(myLight) {
...
LightMaskCubeMap = "mycube";
...
}
------------------------------------------------------
But it work only with terrains and does not work with interiors :'(


Thanks!
