cheesy old-school robot

So I’m working on this cheesy old-school robot. (Image attached) And just like these old-school robots, I want the mouth to light up when the robot talks. In other words, the part that’s yellow should glow when the robot is talking and not glow otherwise. How can do I that?



If you have the moth set to use a separate material from the rest of the robot, you can use a Material IPO to change the Emit value of the material from 0 up to whatever and down to 0 again.

thanks - that appears to be what I want - I’ll check it out
