Shadows not showing properly from Directional Light.

In this video you can see that the sun appears to be moving with the camera, and that shadows only cast at certain positions/angles. If i move to the left the shadow disappears and another shows, if i move forward the same happens too.

Where am I going wrong here?

 

It is only happening with trees, I have a point light that works in a torch and it casts shadows on the wooden support beams of the house. They stay where they are and do not produce the same effect as trees.

 

That's called a specular highlight. It's being caused by having your road too shiny (ie: your smoothness is set too high).

 

I tried to edit the smoothness value but it really did not change much, perhaps its the normal or just the texture issue?

 

For anyone having this problem I have fixed it by doing this:

try bump up the intensity of your directional light

also try increasing the billboard start for trees within your terrain settings (mine is 180)

choose hard shadows for most objects.

thats pretty much it
