This is an Animated Decal which also shows you how you can apply sequences of images to animate what is normally a static decal/displacement, just like the ordinary ones,,, but better!
Yes, you can use this Decal in exactly the same way as the static ones, but by using sequences through "images as Planes", you get an animated result.

And just as you would connect the Texture, Height, Normal and Curvature maps, you do the same here, but with cyclic sequences of images.

Clicking the "Cyclic" option in the "Images As Planes" node, you will get the sequence looping through, frame by frame, animating your decal into life.

Along with the pre-rendered AO, Curvature, Height, Normals and texture images, to get you going, I have included the original Blender file, so you can edit, manipulate, re-colour and re-render any changes you like. THIS DOES REQUIRE AN ADON CAPABLE OF DOING SO, but there are several out there and some are free.
