I change my directlight to moveable type,but it cast bad shadow,why?

As the pic show,my directlight cast bad shadow ,and I just don’t know why ,how to solve this problem?

Hi Chen,

For a movable light you will need to adjust the quality via the cascaded shadow maps.

Using these settings should help but Cascaded shadow maps are limited in their quality as well.

I would recommend looking into Ray Traced Distance Field Soft Shadows if you want shadows for static objects at greater distances if the standard cascaded shadows does not work for you.
