Character appears transparent/missing mouth in export

[jasonbice15]

Hi everyone,

So when I'm working on my timeline everything looks fine, but when I export, my character is transparent and his face is now gone. How can I fix this? I've worked for hours on this project.

Did you set any layers to "Don't render this layer" or have much masking (which often doesn't show correctly in the workspace)?
