Displacement with megascans decal looks really flat.

[stelees]

Hey there,
I have been trying to apply a decal to a road and rendering in vray. The decal applies but it just looks like something has been spilled on the road, not a chunk taken out of it.

The screenshot shows the whole material, the output and the vraydisplacementmod. I noticed also if the amount in the dispmod was too high you could start to see the edging on the UVW for the decal. What I am getting wrong here?

Does it look flat with different lighting? Maybe attach a stripped version of the scene so we can take a look?
