How to adjust baked shadow angle from script?

Distant lights have two properties which affect shadows in lightmaps: Shadow Angle and
Shadow Samples. How could I adjust these properties of from script?

 

This is one way to do it:

Code (csharp):

1. SerializedObject serialObj = new SerializedObject(lightGameObject.light);
2. SerializedProperty shadowSampleProp = serialObj.FindProperty("m_ShadowSamples");
3. shadowSampleProp.intValue = 10;
4. SerializedProperty shadowAngleProp = serialObj.FindProperty("m_ShadowAngle");
5. shadowAngleProp.floatValue = 10;
6. serialObj.ApplyModifiedProperties();
