After all the animations are completed, I started rendering, I chose the Arnold renderer.

First of all, I previewed it and found that my light was not turned on. I pressed the shortcut key 7 and tested again, and found that it was OK.

As there are more lights, the rendering speed may be slower. I chose a resolution of 720.

Then start batch rendering, fill in the frames to be rendered in each scene at once.

Here are my rendering parameters

In order to save time, I found a rendering farm on the Internet and used two machines to render together. This process still took me a lot of time.

Due to the number of operations, I forgot to materialize the wall and made a mistake, because every time the rendering settings need to be set to the file path again.

Finally, organize the rendered files together. For the convenience of editing, this process took about 3-4 days.
