Flat Beauty, AO

Hello,

Last time, I working on my game project, and I need render graphic like as Flat shading on Landscape without DDX DDY - World Creation - Unreal Engine Forums

But I have the following results,

I want something this,


Material of ball,

Material of terrain,

Colors of the materials are the same with blender but, as you can see shadow difference is bigger than expected.
And certainly different of the above example from the link.

I need more AO style, soft little noisy shadows. Is it possible to do?

Where is the light source located and what kind of light are you using?

Yes, the light source is going to make a big difference, in the top picture, there is no shadow.
