Fixing speedtree normals in post.

Hello! I am trying to improve the shaders for my tree “leaves”.

From speedtree, they got normals that face outwards from each “leaf” as you’d expect. But I wish to hide the shape of the planes and implement “bent normals”.

I found a guide to replicate bent normals in the material and implemented it like this:

It looks great for the person that made the guide, making a more unifyingly, rounded shaded look.

But it doesn’t seem to behave quite right for me:

Any suggestions on what I’m doing wrong here?

(Also I noticed during this process that my terrain doesn’t seem to have correct normals either and is only using the normal map, I guess I should fix that as well, or does landscape behave and light uniquely?)

Nobody? This is the tutorial in question:
