Possible to animate map amount in Max?

[Chlebakus]

Hello,

I wonder if it is possible to animate certain map amount.

 

In example, I have material with diffuse and self illuminating map. I want to animate visibility of the illuminating map. It would be handy in making instruments lightting.

 

I already tried it with Arg based visibility in Curve editor, which I added as a controller at illuminating map amount. It is even able to add animation visibility frames when I try to animate it in viewport and material editor. But Model Viewer already showed me that it is not going to work properly. Maybe I made some mistake.

 

Do you have some experience with this, or can you point me in some direction? I have no exact idea how cockpit instrument lights are made. Should I rather go for either duplicating objects or learn something about multi layered textures?
