I started to render an animation (of 200 frames), using 1000 samples, at 1920x1080 pixels, of a scene including a fog object and mesh files (from Alias). It took almost 10 hours for 1 frame, so I think that something is wrong. Is this a usual amount of render time?

I want to keep the quality as high as possible.

I'm using Cycles rendering with CPU, because when I try to use GPU, Blender shuts down.

Specs: AMD Ryzen 5 3600- 6 core processor 16 Gb RAM GTX 1660 SUPER

  • Depending on the complexity of your scene and the precise render settings you’re using, it is certainly possible for a single frame to take 10 hours to render. (A brief internet search suggests a single frame in a Pixar film can take even longer than that during particularly resource-heavy sequences.) It’s hard to say whether or not anything abnormal is happening without more information—perhaps you can upload your .blend file? – Alexis King May 12 '21 at 22:13
  • my blender file is too big to upload here, my file is almost 1.8 GB.. – changam May 12 '21 at 22:46

    With a file of that size, it's not too surprising that rendering one frame is going to take that long! – John Eason May 12 '21 at 23:20
  • I uploaded my ifle , as you said , , it's not too surprising..! okay got it – changam May 12 '21 at 23:27
  • File size alone cannot account for the long rendering time. Fog objects are hard to render (try removing the fog object and see how much time it shaves off), and I think it would be wise to figure out why you cannot use your GPU. Your Nvidia card has CUDA support. Have you tried installing the latest drivers for it? – Joachim May 13 '21 at 04:04
  • Yes I updated my graphic card.. I'm trying to find what is the problem with my GPU – changam May 13 '21 at 11:01

I'd recommend you use the GPU. Blender probably shuts down because you didn't set it to use the GPU at the preferences tab. Go to Edit > Preferences > System > Set it to the GPU you use, NVIDIA is CUDA, AMD is OpenGl. Other things you can do is optimize the amount of bounces in Render Properties > Light Paths > Max Bounces.

Where to find light paths
