Add a "Skip previously-rendered files" option the Iray Background Renderer
THE PROBLEM: If you stop a multi-frame batch render for any reason, including a failure, there is no convenient way to resume the render without re-rendering the frames that had already been completed. You need to manually move those files to another folder, and then put them back later. Or manually submit individual .mi files to the renderer since the tool has no multi-select capability for .mi files.
THE SUGGESTION: Add a simple "Skip Previously-Rendered Files" option when rendering a "folder" of .mi files.
For each .mi file, the Background Renderer Tool would look for the existence of a corresponding PNG file, and if it finds one, it simply skips that file and moves on to the next .mi file.
This should be the DEFAULT behavior.
Any skipped files should of course be properly logged in the message window.
I second this, I don't have anymore votes left but this is essential! I've had renders stall after using the pause for more than once. Anyone that wants to render big projects will find that rendering is painful without this option and is problematic if you have deadlines to meet.
This is partially addressed.
If your render fails and crashes, when you restart it you are given the option to continue or to overwrite the existing images.
But if you cancel your render half-way through for some reason, then you do are not give the option to "continue" when you restart the render.
So there is still room for improvement on the ability to resume both a failed and a "stopped" render sequence.
