In progress Hatsune Miku music video

The character is rendered in EEVEE and everything else is rendered in cycles.

The reason it is split up is because to achieve the cell-shading look and have fine control, she is actually lit by just 2 sun lights, one red and another green.

That would mess up everything else. And in some scenes cycles are also neccesary in order to get correct lighting for the scenes, this shot is on the simple end.

It's an intensive and very annoying process, i hope stylization options become easier later on
