I don't understand what happened. Before when I saved the file it worked fine, but when I came back and reopened it, this problem started happening. (It is most visible with the character's eyes.)
The object is visible in the viewport, but it appears nowhere in the outliner. (Yes, I have scrolled down through the entire outliner to check.) The objects even appear in the preview render and work fine there,(Sorry I couldn't post more than 2 pictures.) but once I press F12 for the final render the objects completely disappear.
I am using cycles render. I am hoping someone might be able to help me, I have searched a lot, but have not been able to find an answer to my problem anywhere.




I'd say most probably they are in the outliner, they may be a child of another object, you may have disabled their render visibility, or they may have an invisible material? there are a couple of possible problems.
