I'm having a terrible time trying to get " cast shadows" working properly in a particular scene. The scene is a city scape with modeled buildings and roads. When I enable "cast shadows" on a directional light the created shadows look terrible! Straight edges of 3d models create shadows that are jagged in places, blocky and low res in others. I've increased the shadow map size to 4096, and I've tried moving the light closer and further away. Even if it did work when closer to the objects that are set to cast shadows, that would not do any good as I need the light on the whole scene so it has to be a fair bit away. Shadows seem slightly better when using a point light but the price of the additional processing overhead is not worth it because the result is still unacceptable.
I'm using Hitfilm pro 2017 but I've been demoing Hitfilm for 2018 and I'm having the same problem there.
Hopefully I'm doing something wrong and someone has a tip to get my shadows looking... well, like shadows.
