As the title says. The object you see selected in the picture is clearly visible in the viewport but vanishes once in the rendered viewport.
I've tried a few common solutions I found online such as checking for rendered visibility in the outliner, checked that it is in the correct layer, set the duplication under objects tab to "none" and even tried re-applying new materials. Nothing has worked so far unless I've done them wrong
Hopefully the screenshot I provided shows that I tried most of the solutions I mentioned above.
Any help much appreciated, thanks.
