Question Edit Terrain Lightmap Scale via Code

Hello,
These fields are not publicly exposed, but you can still edit them using a SerializedObject.
Here is some example code to get you started:

Code (CSharp):

1. // Create SerializedObject from Terrain component
2. SerializedObject s = new SerializedObject(myTerrainGameObject.GetComponent<Terrain>());
3.  
4. // Find and edit properties      
5. s.FindProperty("m_ScaleInLightmap").floatValue = myScale;
6. var currentParameters = s.FindProperty("m_LightmapParameters").objectReferenceValue as LightmapParameters;
7. s.FindProperty("m_LightmapParameters").objectReferenceValue = myLightmapParameters;
8.  
9. // Remember to apply changes when done editing
10. s.ApplyModifiedProperties();
