Good day.

I'm trying to use Houdini Engine (workstation version) to run my SOP HDA 'my_hda'.

'my_hda' is supposed to take some inputs and then cook a bunch of points with attributes. I created and tested it on another device with Houdini FX, and it works well in the .hip file.

My issue is, I failed to have my HDA work with Houdini Engine.

I could start the session, create the /obj/geo1/my_hda node, and it's also fine when I set parameters to this HDA node. I can cook the HDA node without errors or exceptions, but the HDA's geometry is empty.

What could be the possible reasons for this behavior? I've already checked a few things, such as:
- Ensuring that the correct input data is being passed into the HDA (inputs seem to be set up properly).
- Making sure that the HDA is not being culled or having issues with display flags.
- Trying to check if the HDA produces any geometry at all by manually enabling the output of certain nodes in the HDA.

If anyone has encountered this issue before or has suggestions for troubleshooting, I’d greatly appreciate the help!

Thank you!
