Hi.

I'm working on a script that takes in multiple pieces of geo and is dynamically creating a polyReducion node to be independently controlled.
All works perfectly in Houdini, but in Maya my parameters are not showing up. Is there a different setup for hou.ToggleParmTemplate and hou.FloatParmTemplate to be displayed?
In Houdini:


In Houdini with python creating parameters per mesh:



In Maya:



When pressing the RunScript button in Maya, there is a lag for a moment, and that is it.

I cannot find any info on this topic.
I am creating a new template using .FloatParmTemplate, creating a new param in the hda node UI using .addSpareParmTuple, next is getting the parameter from touple .__getitem__(0), and finally setting reference with .set

Have you tried re-syncing or reloading the asset after running the script?

Have you tried re-syncing or reloading the asset after running the script?

Yes, reloading resets everything, where re-syncing will show the asset reduced as intended, but the extra parameters are not showing, so I cannot control the reduction per piece.

I have exactly the same problem but it is slight different circumstances.

I load a HDA into Maya via script using the following line and like yourself, no input parameters show up

pm.mel.eval('houdiniEngine_loadAsset("{}","{}")'.format(hda_path, sop))

If I then load exactly the same asset into Maya using the Houdini Engine menu:
Houdini engine menu -> Load/Load Recent -> My HDA
Then the input parameters show up fine.

THEN, when I run the loadAsset command via script again, the parameters are now visible and editable...

So in short:
Boot Maya
Load HDA via script -> No params
Load HDA via menu -> Params loaded
Load HDA via script again -> Params loaded...

Is there any info on what might be causing this?
