I'm struggling to expose the “Export” button in HDA which is present inside the node of subnetwork. I'm not really good at programming, can any one help me out…!

you can add a parameter from a node to your HDA using the From Nodes tab in the Type Properties

Thank you so much for your response sir. Can you elaborate and explain where can I add parameter to my HDA under Nodes tab in the Type parameters(I'm a beginner in houdini).and Can you explain which parameter do I need to expose for me to export the maps with my HDA.
