Why is my grass shading so weird?
This is my material setup. I wanted to make simple shadeless(single color) grass that accepts shadows. Something like this I guess https://farm6.staticflickr.com/5569/14949490846_72bd065249_b.jpg
This is how the grass looks from one angle which is somewhat close to what I'm aiming for.
This is what it looks like from another angle. This is not what I want.
Here are the normals(the ones in green) of the grass patch
I was always told that on grass the normals should face up but when I did that this is what I got from every angle
Can someone explain to me what it is that I'm doing wrong? All I want is just simple looking grass.
Any answers/advice would be greatly appreciated as I am at my wits' end with this grass.
The last picture that you linked requires that yo rebuild lighting.
I would start with this.
I see that you have two sided turned on in the details panel of your material. As well as two sided foliage so those are covered as far as troubleshooting goes.
If you are using world position offset, as I see you are to achieve the motion of the grass, then switch your lights to stationary or movable. This will allow for the dynamic lighting look you are trying to achieve.
If you painted this with foliage then under your foliage panel where you have your mesh added to that brush there are options for density and other parameters.
Scroll down to Instance settings and make sure that you have cast shadow enabled.
If you are still experiencing this issue after these troubleshoots then please post again.

maybe check double sided geometry
