I am follow the tutorial is called "PDG FOR INDIE GAMEDEV" []
but it cannot show any tops nodes in unity, even I try to download and open the working file that the tutorial is provided.
It still says TOPs Node is None
I am wondering if that is my license do not allow to run PDG or any other reasons? thank you

We introduced TOP network filters starting Houdini 19 to align with the Unreal behaviour. Basically, in order for your node to appear in the list, you must prefix your node name with HE, or HE_OUT if you want it to automatically set the toggle to show results. You can modify the prefixes using the TOP node/output filter option, or disable it entirely.
