To apply the wear effects, you have to activate the parameter in the Materials instance of your StaticMesh or your skeleton, etc. \
\
(You can create your Materials instance dynamic in the logic of your actor.) \
\
To assign the wear level, you have a float parameter ranging from 0 to 1.

In the logic of your actor, it is also possible to act on all the parameters of the material. If you want the intensity of the emissive to be progressive according to an area of your level, you can call the parameter that interests you and modify it in real time.
