[Sidefx-houdini-list] Problems with toggle in otl

If you want the toggle to switch between two different operators inside your object, you could put in a switch SOP and have the toggle control the "input" parameter of that SOP. Then set the display to the switch SOP and it will always show one or the other of its inputs.
If you want to switch between two objects (say in a DA), then use the Display parameter that Robert was mentioning.
Then put the channel reference in the Display channel of the object to be 1 or 0, depending on the state of the toggle. If you want it to be the opposite of the toggle, then use:
Both of these methods avoid using callbacks.
Hope this helps.

Objects have a display parameter that you can use instead of the display
flag. It is found in the Render tab on a geo object and the Subnet tab
of a subnetwork. Simply click on the checkbox to use this parameter in
place of the display flag then write a channel reference from here to
your asset's toggle.
I'm not sure if this is what you are looking for but this is what I
would do in this case.
