The Question is simple, (if possible) how do i Make an animated Decal?

I think "animation" of a decal is limited to:

 

Fading

Stretching

Sliding

Color Change

Combo of above

 

Image you stuck a real decal on a wall.  That's it.  Can't change it to a different looking one, which is what you'd have to do to "animate" it the way I think you want to.

 

Might have to put a linedef one unit away from the wall and make its front middle an animated texture.  That, I know, works.
