I was trying to render a sequence of about 25 frames animation. It took more than 4 hours to finish rendering using arnold. Once it finished, it started rendering procedure again from 0% without me interfering or pressing any button. After trying to stop the second round of rendering, I realised that no images were saved in my directory. Why this happened? Should I leave second round rendering finish? That would take another 4 hours. Why images were not saved? Actually, only a single image was rendered. But I set 25 frames in the rendering settings.
I followed rendering settings according to video tutorial here https://www.youtube.com/watch?v=_F0klwCw2m8
Thanks and looking to hear from you.
