This is a huge feature I’ve been wanting ever since I needed it with UE3. The sun rarely produces sharp shadows in real life, yet I can never get a directional light to cast variable penumbral shadows, where the shadow gets increasingly softer further from the shadow casting object. I know you can do this with point lights by setting the light source radius (though it doesn’t seem affecting the shadows in Rocket. It worked as expected in UE3). Is there a technical reason why this is not supported with stationary directional lights?

Edit: Just to be clear, I’m talking about baked shadows, not realtime. Though realtime would be awesome!
