I have about 700 scenes in SU, each one representing a frame in the animation sequence.
When I run the render-animation from scene 1 to 700, the CPU (4 cores) is working at about 25% for about two hours with no images produced. There’s no GPU activity. What is it doing?
Later, after about two hours, the rendering starts. However, it gets to producing image 54 of 700, then it stops or hangs. At this point, there’s no CPU activity, no GPU activity, the render button is still grayed out and the blank DOS CMD screen is still open.
