Can anybody figure out why this mesh text shows fine in viewport render , both from camera view and in 3d space as shown below , but when I render it out is is invisible… The material setup is also shown below. As you can see , nothing is set to indirect or mask or anything in the outliner so I am stumped. Most likely something silly….

Thanks in advance for any advice
