How Manga Bunny was made:

100 mm lense for flat view compression.
Model imported, flatten approx 95%, placed
above a flat plane, then rotated 90 degrees
so that camera is looking straight down.
Image Based Lighting is the White Tile.
3D Type added and, as a new effect I have
been playing with- a side spotlight to
re-create some 3D effects.
Post-Processing dialog includes gamma and
increased saturation of the colors by about
20%. I have no specific formula for this- I
adjust the sliders in the Post-Processing
dialog until things look sufficiently "Toonish".
