I am having trouble applying Anything Glows (AG) and getting multiple light sources from it. What I am trying to do is simulate the light being generated by a molten lava field. What I have is a terrain in which I am using a flat plane as my lava field. Where the plane pokes up through the terrain, I would like some light to illuminate the surrounding terrain.

I have placed the lava plane into the vertex modeler and subdivided it many, many times in order to get a fine mesh on the surface to assure that at least some mesh centers (or mesh vertices) are uncovered at the points where the lava plane pokes above the terrain.

I then turned on AG for this plane. I have used both the vertex and the facet light source options but all I ever get is some light peaking out at the outer edge of the lava plane, but never on the surface. I have also tried inverting the normals on the plane and that had no effect.

I have also tried using an actual 3d vertex object on which I again subdivided the top surface multiple times and this also did not work.

Any thoughts or suggestions on how to make this work would be greatly appreciated.
