Stylized Underwater Scene (Python API / MEL Script)

For a children concert about Tabaluga (classic german children show) I had to create some sequences. I worked in Unreal Engine 4 to render it. Except for the bubble particles and the far away background I created everything inside zBrush, Substance Painter and Maya. The post production was done in Fusion.
For the animated sea anemone I actually made a python script to quickly create animated meshes with bones and the hair system in Maya.
The format of the images/video is due to the projection used on the concert. It had to have a very unusual aspect ratio.
