I created a short animation and after rendering it, I must have had one/some of the nodes not set correctly. I want to go back into the file and see what I did wrong, but when I open the file up it defaults to the rendered window.
I have gone through all the window settings and cannot find where/how to re-open the nodes panel to make adjustments and then re-render it. Sorry if this was answered already. I searched the forum in various ways and could not find this exact issue. I consider myself a novice-intermediate level Blender user.
