Question Is there any solution that LightmapParameters via script ?? version 2019.2

Code (CSharp):

1. // Parameter
2.     LightmapParameters m_defaultLightmapParameters = new LightmapParameters();
3.     private static SerializedObject GetLightmapSettings()
4.     {
5.         var getLightmapSettingsMethod = typeof(LightmapEditorSettings).GetMethod("GetLightmapSettings", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Static);
6.         var lightmapSettings = getLightmapSettingsMethod.Invoke(null, null) as UnityEngine.Object;
7.         return new SerializedObject(lightmapSettings);
8.     }
9.  
10.     private void GetValue()
11.     {
12.         SerializedObject baseSettings = GetLightmapSettings();
13.         SerializedProperty lightmapParameters = baseSettings.FindProperty("m_LightmapEditorSettings.m_LightmapParameters");
14.  
15.         m_defaultLightmapParameters = lightmapParameters.objectReferenceValue as LightmapParameters;
16.     }
17.  
18.     private void SetValue()
19.     {
20.         SerializedObject baseSettings = GetLightmapSettings();
21.         SerializedProperty lightmapParameters = baseSettings.FindProperty("m_LightmapEditorSettings.m_LightmapParameters");
22.  
23.         lightmapParameters.objectReferenceValue = m_defaultLightmapParameters;
24.  
25.         baseSettings.ApplyModifiedProperties();
26.     }
27.  
28. // laurenth-personal/lightmap-switching-tool
29.  
30. private IEnumerator BuildLightingAsync(Scene lightingScene)
31.     {
32.         Lightmapping.ClearDiskCache();
33.         var newLightmapMode = new LightmapsMode();
34.         newLightmapMode = LightmapSettings.lightmapsMode;
35.         // setting part
36.         LightmapEditorSettings.prioritizeView = true;
37.         LightmapEditorSettings.directSampleCount = 32;
38.         LightmapEditorSettings.indirectSampleCount = 512;
39.         LightmapEditorSettings.environmentSampleCount = 256;
40.         LightmapEditorSettings.bounces = 2;
41.         LightmapEditorSettings.maxAtlasSize = 1024;
42.         LightmapEditorSettings.lightmapper = LightmapEditorSettings.Lightmapper.ProgressiveGPU;
43.         LightmapEditorSettings.mixedBakeMode = MixedLightingMode.IndirectOnly;
44.         LightmapEditorSettings.bakeResolution = 2;
45.         LightmapEditorSettings.enableAmbientOcclusion = false;
46.         LightmapEditorSettings.padding = 2;
47.         // parameter part
48.         GetValue();
49.         m_defaultLightmapParameters.name = "Test";
50.         m_defaultLightmapParameters.antiAliasingSamples = 256;
51.         m_defaultLightmapParameters.limitLightmapCount = true;
52.         m_defaultLightmapParameters.maxLightmapCount = 3;
53.         SetValue();
54.  
55.         //LightmapSettings.
56.         Lightmapping.BakeAsync();
57.         while (Lightmapping.isRunning) { yield return null; }
58.         EditorSceneManager.SaveScene(lightingScene);
59.         EditorSceneManager.CloseScene(lightingScene, true);
60. }

Oh.. It doesn't Work..

I have no idea that how to access to lightmapParameters via code

! help me !

 

Yes. I read it.

So, I tried baking another way.

First, I wrote a script that changes the lighting parameter on the 'Lighting Editor Settings' window.

Second, I changed the parameter's properties via the script.

Finally, I tried baking Light via another script for light baking.
(not the Inspector of lighting settings but the custom tool of lighting settings like on the thread script.)

And then I found In the inspector the lighting parameter name is only changed.

In the Dropdown of the parameter, except for the changed name, the custom parameter item does not exist.

But, there is not any error in the baking process.

So, it is really applied to the baking process?

 

If you want to see your created lightmap parameters via script into the list, you must save your lightmap parameters as asset into your project files
https://docs.unity3d.com/ScriptReference/AssetDatabase.CreateAsset.html

Code (CSharp):

1. LightmapParameters a = new LightmapParameters();
2.  
3.             a.name = "Lighting Box Very-Low";
4.             a.resolution = 0.125f;
5.             a.clusterResolution = 0.4f;
6.             a.irradianceBudget = 96;
7.             a.irradianceQuality = 8192;
8.             a.modellingTolerance = 0.001f;
9.             a.stitchEdges = true;
10.             a.isTransparent = false;
11.             a.systemTag = -1;
12.             a.blurRadius = 2;
13.             a.antiAliasingSamples = 8;
14.             a.directLightQuality = 64;
15.             a.bakedLightmapTag = -1;
16.             a.AOQuality = 256;
17.             a.AOAntiAliasingSamples = 16;
18.             a.backFaceTolerance = backfaceTolerance;
19.  
20.             //LB_LightingSettingsHepler.SetLightmapParameters (a);
21.             LightmapParameters.SetLightmapParametersForLightingSettings(a, Lightmapping.lightingSettings);
22.             AssetDatabase.CreateAsset(a, "Assets/Lighting Box Very-Low.giparams");
23.  

 

Thank You! . I will try it.

 

tested and works well
