Shadows and Object Size

Does scale of objects effect shadows?

I have a scene with hard shadows and the shadows are very blocky.

I wondered if I made the objects bigger (they are scaled small) would the shadows appear better or does it make no difference? (larger scaling with more distance from shadows, although the shadows would be bigger too) Thanks

 

It depends.

Directional shadows span a particular range in front of the camera, set in the Quality settings. If your object is very small, and this range is large, then yes. You could scale up the object, or reduce the Shadow Distance.

However if you have a small object that's far away, this is a difficult situation as the directional shadows always go from the camera to the shadow distance range.

 

Thanks for the detailed response!
