Disable shadows with using Lightweight Pipeline Render in runtime

Hi!
Unity 2018.1.1
How can I disable shadows with using Lightweight Pipeline Render in runtime?
QualitySettings.shadows = ShadowQuality.Disable dosnt work =(

 

Hello!

1. Select LightweightAsset file, click on little gear -> Edit script


2. Find ShadowSetting property declaration in LightweightPipelineAsset.cs file, remove private modifier near set and save your changes.


3. Create new script "RenderSettings.cs" and paste this code:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Experimental.Rendering.LightweightPipeline;
3.  
4. public class RenderSettings : MonoBehaviour {
5.     public LightweightPipelineAsset lightweightPipeline;
6.  
7.     private void Start()
8.     {
9.         lightweightPipeline.ShadowSetting = ShadowType.NO_SHADOW;
10.     }
11. }
12.  

4. Create empty gameobject, add Render Settings component, assign LightweightAsset for Lightweight Pipeline public variable.


5. Press play and shadows will disappear

Note that script changes graphics settings permamently, not just in Play mode.

 

Hi all!
Unity 2018.3.0 and Lightweight 4.6.0

The method described above does not work. How can the new version of Unity enable / disable shadows in runtime?

 

Only Work in Editor
Not Work in Android

 

You can. The difference is those shadow settings are controlled by the LWRP asset. So you have to access this.

((LightweightRenderPipelineAsset) GraphicsSettings.renderPipelineAsset).shadowDistance = distance;

Here you can set the shadow distance. Not sure if you could deactivate shadow with a bool. But a distance of 0 should do the same.

 

You can access those values using ugly reflection:

Code (CSharp):

1. private FieldInfo lwrpaShadowField = null;
2. private FieldInfo lwrpaSoftShadowField = null;
3. private FieldInfo lwrpaShadowResolutionField = null;
4.  
5. lwrpaShadowField = lightweightRenderPipelineAsset.GetType().GetField("m_MainLightShadowsSupported", BindingFlags.NonPublic | BindingFlags.Instance);
6. lwrpaSoftShadowField = lightweightRenderPipelineAsset.GetType().GetField("m_SoftShadowsSupported", BindingFlags.NonPublic | BindingFlags.Instance);
7. lwrpaShadowResolutionField = lightweightRenderPipelineAsset.GetType().GetField("m_MainLightShadowmapResolution", BindingFlags.NonPublic | BindingFlags.Instance);
8.  
9. lwrpaShadowField?.SetValue(lightweightRenderPipelineAsset, qualitySettings.shadows);
10. lwrpaSoftShadowField?.SetValue(lightweightRenderPipelineAsset, qualitySettings.softShadows);
11. lwrpaShadowResolutionField?.SetValue(lightweightRenderPipelineAsset, qualitySettings.shadowResolution);
