Hi @jkiser,
Very interesting question! Where are you storing the URL of your publish? Is it on a Published File entity? I’m not very familiar with Marmoset, but I have an idea how we can get a URL embedded in Shotgun based on a URL in another field.
In my example here I’m using the description field on the Published File entity, but you can use any custom text field.
First I put the URL into my text field, here I’m just using wikipedia:
Next, I’m going into design mode on my Published File and creating a new tab:
Then on this new tab I’m putting the field code of the description field in curly brackets so the contents of the field will get expanded:
Finally I save the page. Now on this “Embedded URL” tab on my Published File detail page I can see wikipedia.
This will all be predicated on the Marmoset URLs allowing embedding in other sites iframes. Do you think this might work for you?
