Removing Aliased Shadows

I have created the basic project and noticed that there is some heaving aliasing in the shadows. Not sure how to solve this, and all the forum posts I’ve seen are from people wanting to know how to turn off anti-aliasing, which is not what I want to do. Here’s an image of the problem. You can see aliasing on the shadow along the far wall.

EDIT

I was able to reduce the aliasing by increasing the light map resolution of the mesh. However, this also made the shadow extremely blurry. The other shadows are really clean.

i checked out the same corner and while it looks a lot better, there’s still some distortion. what are your quality setting at? mine are on max. seems like an engine limitation though.
