I've got a generative hda that simulates some particles, and then another very simple hda that imports these into a cop2 network and renders 2000 frames of this to disk. I'm wondering if there is a way to run over multiple ‘Template Nodes’ with the HDA processor.
I tried:
1. Creating multiple instances of my generative asset in the scene with different parameters.
2. Creating a wedge node with a string attribute that stores the paths to these nodes.
3. Referencing the string with @path (my attribute name) in the Template Node parameter in the hda processor.

Unfortunately even though I see that the path attribute changes, the parameters don't change for the hda.

Sorry if this is unclear or not the way to go about it. I'm fairly new to PDG. At the moment I'm setting the HDA parameters that I like, then rendering it out. But then I must wait for the render to complete before proceeding to render the next instance of my hda, and I'd like to leave this overnight.
