In the compositing process of this work, I used a layered rendering workflow. This mainly involved further adjusting the lighting of the characters in some scenes using different light channels in the post-production software After Effects, as well as adjusting the depth of field effect controlled by the Z channel.

For example, in the image above, I used a light channel to control the cyan light on the right side of the character to only illuminate the character. During rendering, the light layer was rendered separately, and the intensity and color of the light were further adjusted during post-processing, which increased the controllability of the image.

The compositing process for 3D animation is not that complicated. All the visual elements are controllable in the software, so what I do in the composition part is to control the overall visuals, such as adjusting the contrast and curves.
