Trees - Lightning bug

Hey Community,

I found a lightning bug (why are all my bugs lightning bugs :D) which i’m not able to solve alone :expressionless:

Theres a flashlight and a Tree. The Tree is not in the radius of the flashlight but the tree is lighten up like there’s a sun in front of it (look at the picture) :S

It’s a problem with a shader, but what’s the problem? ._.
The Trees are from the “Terrain Assets” published by Unity Technologies :wink:

Example Picture:


Btw, I get the same or a similar problem.

Very annoying, and the only way I know how to fix it is very hacky and a lot of work, involving cache-file overwriting:
