I am trying to output houdini point data for use in Unreal Niagara assets.

Following along with the Houdini to Niagara workflow tutorials:
https://www.sidefx.com/docs/unreal/_niagara.html [www.sidefx.com]

I have gotten the Unreal side of this working, and am able to use the supplied example Unreal Niagara assets, however on the Houdini side I am not able to use the Labs Niagara ROP [www.sidefx.com]node. Loading the supplied .hip files results in errors that the node definition is not complete and when attempting to set up my own network am not able to find the Labs Niagara ROP node at all.

I am wondering if I am missing a step somewhere but have not been able to find any documentation or way to install/enable the niagara ROP node.

I am experciencing the exact same issues : Demo files inconsistent and not working. In my experimental attempts to export a Houdini pointcloud to UE5's Niagara particle system, it appears I need the Labs Niagara ROP installed into Houdinis' Labs.

The problem is that I cannot find any Labs Niagara ROP object in the latest downloaded and installed Labs build...

I'm I doing something wrong ?
Is this Labs Niagara ROP node dead ?
Any clue ?

It's there in the current production build (19.5.716), as a SOP node, not an object.
