Ooopsss I confused the SpaceMan… sorry for that…
Glow Material is simply the ‘GLOW’ material in the material browser. Nothing I made. It has to sliders in the S1 section which allow you to tune it in brightnessss and glow/hazenesssss.
Then GlowTexture is a made up term for a high contrast texture consisting out of black background and some bright color specs. Like a Zeeble texture with black backround onto which you paint bright yellowish ,redish, whiteish, or everythingtogetherish squares.
Then assign that texture to an object which carries the glow material and you have all the glowing squareness you can take!
If the background in the texture is not black, then it will also start and glow. So keep it as dark as possible as it will ‘pop’ out later when you play with the glow parameter… I am sure you got the point.
And… it only shows in best render. Not much to see in preview render… Which in itself can be rather confusing!
