Changing material colors

alo everyone,

so I’m trying to make a blade with an energy covering that will appear and disappear, but i have 1 problem.

i don’t know how to change the color of the material in an animation?, this is not the textures, but just the color ant transparency of the material.

thanks everyone!!!

place your mouse cursor in the material window, and press ‘I’ for a menu of material ipo types. once you select one, you can see your ipo in the ipo window by choosing ‘material’ from the pull-up menu on the ipo window header. advance several frames, change your material settings, and press ‘i’ again, etc.
