Alphablend/Lightblend

BlitzMax Forums/BlitzMax Beginners Area/Alphablend/Lightblend

I can make objects transparent/alpha blend using the SetBlend command, but how can I make objects Lightblend (make objects appear to glow)?

I understand that it requires two images - one of the actual object and another to show lumiescence of the object, but how do I set this up in Max? Drawing the alphablended object over the top of the brightness object doesn't create a brighter object, just a semi transparent, pale object.

Is there any code available just to create a bright image?
