I am trying to get grass that look like the one in Dauntless - Fortnite - the Witness - Zelda:botw and many other stylized games. It is flatshaded, but cast no shadows and recieves shadows from other objects. And it also gets brighter when the light shines from above.
Here are some examples:
from the Indiegame woodbound (gif)
I managed to reproduce it in Blender internal render:
No texture, only planes, lightsource is a sunlamp.
The Vertexnormals of the planes are looking straight up (blend4web addon helped me there).
In Cycles I tried mixing up a diffuse + translucent shader, edited the vertexnormals aswell, but it doesnt get the flatshaded look.
It only looks good, when all the planes face the same direction, or the light source is mainly hitting the Front. If the camera is looking at the plane at an angel, the color gets darker. If the camera looks at the backside of a plane its dark.
I searched the web for a view weeks now, the only thing that helped (and let me recreate this effect in blender-internal) was, to let the vertex-normals of the plane face straight up.
Maybe you guys have some Ideas for this stylized shader in Cycles :)
