Light Problem With Leaves on my built project

Hi everyone,

I am a little confused on my first finalized project.

On the start i had a problem with the shader used on leaves of my trees. If some part of light touched a leaf of a tree, all leaves of this tree were illuminated.
So i downloaded a new shader here : Unity Asset Store - The Best Assets for Game Making

I updated my trees and it’s working fine in my project, and there is no errors in console when i built the project.

However, when i launch my built version all leaves of the game are completely dark.

I don’t understand at all how to fix this problem.

Could you help me please ? Thanks by advance.

I just realized that if i turn off Unity, leaves of my trees are completely dark when i come back on my project.

So building is not a problem.

I am completely lost here. My first shader illuminated all leaves, and the new one let them completely dark.

What am i doing wrong ?

Well i finally found by myself.
I wasn’t using my new shader correctly, i hadn’t spend enough time to study it.

So it was all my fault, sorry to have create a useless post.
