Stumbled on this by total accident. (I think Vue 4 Pro had a feature similar to this but it never worked for me) Last night I started to render an image at around 8pm. At 11pm I came and checked on the image and it was only half way done so I decided to stop it and would render the image when I had the time to let it finish in total. Today when I came home from work I reloaded my file with the intent to render my scene from start to finish. To my surprise, V5I remembered where it left off the last time and started to render from there!!! This means that the next time V5I tells me it will take 30 hrs to render an image I can do it over several days time!!! I was and still am thrilled!!! No longer do I have to leave my pc on over night, I can render part of the image, save the file, and come back and reload the scene the next day to finish the render. V5I is awesome!!!!
