So when I render my composition in Newton 2 what happens is that Newton 2 closes and a separate composition is made. What if I want to change or edit something again in the composition. Cant I go back in Newton 2 and edit things? Is there no going back? I had to delete the composition 3 times because it didnt came off the way I wanted and then there's no option to go back to Newton and make some changes. Please help.
