Anyway here is my fix for “glowing”.
It does not use layers but rather a “glow texture” that I used to texture the columns/lights. This texture was created in Blender and Gimp (see image below). The vertices count is up 300+ but the light is now a cylinder shape of which half is effectively hidden and can be removed to bring the vertices count below 6,000 again
@JCPalmer : I’m not sure it is a movie - more a special episode of “Red Dwarf” called “The Promised Land” that I saw on Prime Video. Instead of 30 minute episodes, this is series 13 that is a single 90 minute episode. The actor who plays “Kryten”, Robert Llewellyn, tells horrific tales about the makeup procedures he had to go through. Anyway, for you Jeff, enjoy my glow fix and some sound 
Use Firefox as I have not yet added the Chrome sound fix as I want to add a GUI setup first.
The whole series is on Prime Video.
