I'm working on a project which is barely more than a fancy slide show, changing an image on a plane every few seconds.
The issue is that every time I render an animation, it does it frame by frame, repeating the same renders over and over again until the "slide" changes.
What I'm searching for is a way to opt-in to lazy rendering, where unless there's a known tween in progress, Blender just holds the frame. Does something like this exist, and if not, is there any way to get Blender to skip renders?
EDIT: I found this link (Render optimization when frames are almost the same), but it's not very helpful and relates to similar frames rather than frames which are exactly the same.
