Hi guys,
I’ve always used Render Elements in my projects, for the first time now, I get an Image I/O error whenever I enable it and try to render htem with Vray Frame Buffer. The error happens in different files/projects/scenes, it’s really frustrating because I can’t render anything at the moment.
Any help would be greatly appreciated.
Thanks a lot! 
Do you mean you can’t render at all when using elements?
Usually the I/O error appears when e.g. a save path does not exist (has changed since the scene was last opened) or when the destination drive is full, or possibly
that the save destination folder is read-only.
You could also check the asset tracker to see if anything is missing/incorrectly linked.
Another possible fix is to merge all to a clean scene and add the elements again to clear out anything unusual.
You can also post/link a very simple scene where this error occurs and someone here will be able to figure it out
