Vertex Paint with fake height between 2 materials? How?

Klodza

Hi guys, I got to the vertex paint stage in my level and I am confused how to go about this issue. I am trying to create fake height difference between my top layer (wallpaper) and bottom layer (plaster).
I am still learning unreal so figuring this out seems like black magic. 

This is what I got so far, (the mask for the brush is just a placeholder). You can see that it looks super flat and not good. 


The top layer is essentially the copy of the bottom layer with the same parameteres.




This is what I'm trying to achieve: 


I will appreciate any help.

First of all, the height map should be in the pattern of how wallpaper peels off a plaster wall. So search for examples of peeling wallpaper to use as inspiration. Think about what parts of the paper peel away first, those will be the darkest parts in your height map. What are the parts that are the last to peel, those are the brightest in the height map.

Something similar to this would be a good starting point:
