@br1 By clicking "Render to MPlay" on the mantra node. Using Render View is an option I'll pass along, but I'm trying to support their current workflows, if possible. The flipbook preference is great because I can just set that in the background and it starts working how they would expect.
@ejr32123 Unfortunately, if select "listen for renders" in a second mplay session, renders still go the the first. The only way I can stop it from going to that original mplay session (the user cannot see or access) is to click render > disconnect before hitting render > listen for renders in a second mplay or killing the first mplay process.
