If you're talking about animating the intensity then its just as simple as every other attribute that you can right click and "set key". You can even tweak the curve in the graph editor. Anything other than that, you will have to grab that "shader glow" shader that's always there in Hypershade and edit the glow properties on that. Keep in mind though, this is the master glow and will affect any shader with any glow intensity (which can be a good or bad thing). Hope that helped!
Yes that did it. I had no idea I could right click on the attribute NAME and open a menu. Thank you. You mentioned it would then be in the Graph Editor. I set two keys but I don't see the attribute in the graph editor yet. What am I missing?
