USD importer supported in unreal 4.18?

I found the USD importer under …\Engine\Plugins\Editor\UDSImporter but I can’t find any information on using it. Is this operational and is there any information on using it properly? Ideally from Houdini?

thanks!

Did you ever find out anything about this? My understanding is allows easier use of real world data ? Love to know more myself having just heard about it via 4.24 release.
