Substance Designer in Houdini - Procedural Tool for Unreal Engine

I’ve been trying to create a procedural brain coral placement tool in Houdini for Unreal Engine to work in the following way:
Generate random brain coral height map → Displace Geometry → Place on grid
In order to dynamically generate height maps I have been using the Substance Designer COP inside Houdini where I supply the height map to the geometry.
However, when I try to create a Digital Asset for UE5, the displacement does not translate over - I assume this is because I am using a Labs plugin to achieve it.

My question is this: Has anyone successfully using the Substance Plugin inside Houdini to create procedural tools for Unreal Engine?
