What is wrong with the shadows? (SpeedTree)

I have already bought the UE4 SpeedTree subscription and as always it’s happening again. I have these problems on the shadows’s trees as in all the object/3d Models that I tried to introduce into the program. I don’t really know how to fix this problem and I’m really tired of looking around how to solve it.


Looks like you perhaps need to increase the shadow resolution on the terrain?

Or maybe build lighting with at a higher quality (production, etc)?
