How do I drive a Switch SOP input from a Wedge TOP attribute Aug. 8, 2026, 11:28 a.m.

I'm doing something similar, I have an HDA to expedite wedge params like folder paths, files names etc - on my HDA I have a "Preview Wedge" slider that will swap wedges, here you might just use the HDA param to control the wedge and the switch -

python script module in HDA:
def select_wedge(node, index):
    # ← CHANGE THIS path to your actual Wedge TOP
    top = node.node("topnet1/wedge1")
    
    if top is None:
        return

    pdg = top.getPDGNode()
    if pdg is None:
        return

    # Prefer matching by wedgeindex attribute
    for wi in pdg.workItems:
        if wi.intAttribValue("wedgeindex") == index:
            top.setSelectedWorkItem(wi.id)
            return

    # Fallback
    if 0 <= index < len(pdg.workItems):
        top.setSelectedWorkItem(pdg.workItems[index].id)

Callback script on int parameter:
kwargs["node"].hdaModule().select_wedge(kwargs["node"], kwargs["parm"].eval())

This has worked for me before https://www.youtube.com/watch?v=oSotagH9K0g [www.youtube.com]

Anyone else notice H21 pyro viewport rendering issues? Nov. 27, 2025, 3:24 a.m.

I hoped this was just a fluke in one of my files but it's a constant issue for me - if I sim pyro I constantly get issues where my pyro volume just disappears while I click through the timeline. Oddly, if I quickly scrub the timeline and release, pyro renders, which makes me think this is just a bug with H21 - in this video I was trying to show colleagues the differences between attribs but this bug makes it kind of sad/hard to illustrate

I've got an amd rx7900xtx (4090 equivalent) and like 7k$ worth of other computer components

Has anyone else noticed this issue?

Also, does anyone know where/how I can submit a bug report?
