Question Editing visual environment sky type in game in HDRP 12.1.7

Hey, is it possible to edit the visual environment sky type in game?
I can edit the sky type manually in game but editing it through code seems to have no effect no matter which value i set it to

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Rendering;
5. using UnityEngine.Rendering.HighDefinition;
6.  
7. public class Test_VisualEnvironment : MonoBehaviour
8. {
9.   [SerializeField] private VolumeProfile Profile;
10.   private VisualEnvironment visualEnvironment;
11.  
12.   private void Start()
13.   {
14.     if (Profile.TryGet<VisualEnvironment>(out VisualEnvironment ve))
15.     {
16.       visualEnvironment = ve;
17.     }
18.     visualEnvironment.skyType = new(2, true);
19.   }
20. }

 

Hey greenlaser, I am having the exact same problem with VisualEnvironment, and it's driving me nuts. I'm even using sharedProfile, which I understand to be the correct way to ensure you're affecting the Volume that you see in the Inspector:

Code (CSharp):

1.     private Volume skyVolume;
2.     private VolumeProfile profile;
3.     private VolumetricClouds volumetricClouds;
4.     private VisualEnvironment visualEnvironment;
5.  
6.     void Start()
7.     {
8.         profile = skyVolume.sharedProfile;
9.         profile.TryGet(out volumetricClouds);
10.         profile.TryGet(out visualEnvironment);
11.     }

Here's the bizarre part: Everything works as expected for the 'volumetricClouds' defined above, but NOT for the 'visualEnvironment', even though both are referring to the same shared profile Volume 'skyVolume'.

If I change parameter values in the VolumetricClouds Override of this Volume, they not only affect the volume clouds in the scene perfectly, but I can see the values change in the Inspector.

But if I change parameter values in the VisualEnvironment Override from the same Volume, they do nothing. If I query the profile, the parameters report that they have indeed changed; but neither the Game View, Scene View or Inspector reflect those changes.

Did you find a resolution? Does anybody else have a resolution?

I am using Unity 2022.2.18 and HDRP 14.0.7.[/QUOTE]

 

I found the solution that worked for me:

A) I had to set the profile AGAIN before the additional TryGet:

Code (CSharp):

1.     void Start()
2.     {
3.         profile = skyVolume.sharedProfile;
4.         profile.TryGet(out volumetricClouds);
5.         profile = skyVolume.sharedProfile;
6.         profile.TryGet(out visualEnvironment);
7.     }
8.  

B) When I tested the parameters for 'visualEnvironment' I was querying the skyVolume.profile.components[int].parameters[int]' so got faked out. As near as I can tell, because I didn't repeat the 'profile = skyVolume.sharedProfile;' assignment before the 2nd TryGet above, my 'profile.TryGet(out visualEnvironment);' actually created a clone of the profile; so I was changing parameters in the clone, and reading them back from the clone. Total fake out.

As soon as I inserted the 2nd 'profile = skyVolume.sharedProfile;' before the 'profile.TryGet(out visualEnvironment);' AND changed my verification query to 'skyVolume.sharedProfile.components[int].parameters[int]' then everything worked as expected and reported back as expected. And the values in the Inspector reflected that.
