Ok so I have been working on this for a long time now and upon going to render... it has hit this point in the render and just styarted to go so slow i dont even know if it is renndering anymore, its saying 14 hours and is constantly climbing, should I jusr restart the render or let it carry on, or has the render just crashed or something? Note that this clip is about 30 seconds long
It appears you're rendering out to an MP4 in which case you'll lose whats been done. Best advice is to render out as an image sequence then convert afterwards. That might also help diagnose what or at least where your hitting a bottlenck.
