Basically,we have a gizmo with a couple knobs, and a callback that would update the path on the internal write knob when those values were changed. Since it wasn't working, I added the knobs and callback to a Write node, so we could just give people the Write with a couple extra controls. However, once I put those knobs and the callback on the Write node, put the Write node into a gizmo, and picked up the knobs it seems to render fine. Like I said, I'm not sure why it works that way, but I'm glad it does.
