Animated lightmap or UV camera


We want to projectionmap on a physical object. I have the same object as a 3D object and it is unwrapped.

For the content i want to use unreal to create some effects. For example al lightsource that is animated, changes colors and its travelling along the object.

Now i want to capture the UV map with the light effects as an animation so i can load it in a Disguise server to apply it again on the 3D model.
Does anyone has a solution to capture the UV map with the animation/light effects? Is there such a thing? Or can we create a animated lightmap?

Any suggestions?
