I used custom cel shaders and grease pencil in EEVEE to create an animated music video that has 2D characters in a 3D space! All models(such as the vehicles, house, egg tree, even the grass) + materials created by me. I even used BGE to create a fake video game for the characters to play in the beginning! I wanted to do absolutely everything in Blender. It took about three months to make. Hope you enjoy :'-) <3
