I've deleted all my other UE installs except 4.25.2 and reinstalled Houdini 18.0.532, ticking ‘install engine for Unreal’ on install.

The installation instructions claim simplicity - the plugin will be available in Unreal.

This should mean I can drag/import a hda/hdalc into UE4 and use it, but it's not appearing in the plugin list in UE, nor is it copied to the folder the installer says it should be in: “C:\Program Files\Epic Games” has nothing in it at all, the folder is empty but Unreal works!

Following these instructions around in circles:

I have it working in version 4.24.3 & 4.25.2, although I normally stay a version or two behind and am currently working in 4.24.3.

Maybe you don't have the plugin enabled?
