I replied to this answer on your drizzt in bryce post.. I'll paste it here: Two possibilities. If you've got photoshop, it's really easy. Just mask render the blade, then load the render, apply the mask render as an alpha channel, select the mask, and apply a glow filter. In Bryce, it might not turn out as well, but copy the blade (just the blade if possible), and make it a little bigger. Find the green light material in the Complex presets, change the color to blue, and apply it to the enlarged blade. Play with that until you get a glow you like. =) Hope that helps. Rosh
