GI - script

(posting here because I think I'll have a better chance of getting an answer)

Originally I was just trying to modify the EmissionScale in the shader and was referred to the following link...

http://answers.unity3d.com/question...ls-emission-scale-at-runtime.html?sort=oldest

I'm just trying to toggle the emission on/off. The documentation (link below) says there are 3 parameters, but it will only accept 2. And I am puzzled as to why I can't control the emission with the emission value? Instead I have to jerk around with the color. In any case, it's not working, can someone give me a hand with this? Thanks.

Code (CSharp):

1. public class Lights : MonoBehaviour
2. {
3.     private Renderer renderer;
4.     private Material material;
5.     private float emissionValue;
6.  
7.     private Color white = new Color(1f,1f,1f,1f);
8.     private Color black = new Color(0f,0f,0f,1f);
9.  
10.     private bool isOn = true;
11.  
12.     void Awake()
13.     {
14.         renderer = GetComponent<Renderer>();
15.         material = renderer.sharedMaterial;
16.  
17.         emissionValue = material.GetFloat ("_EmissionScaleUI");
18.  
19.         Debug.Log (this.transform.name);
20.         Debug.Log (emissionValue.ToString ());
21.     }
22.  
23.     public void ToggleLights()
24.     {
25.         isOn = !isOn;
26.  
27.         if (!isOn)
28.         {
29.             Debug.Log ("Off");
30.             DynamicGI.SetEmissive(renderer, (black * emissionValue));
31.         }
32.         else
33.         {
34.             Debug.Log ("On");
35.             DynamicGI.SetEmissive(renderer, (white * emissionValue));
36.         }
37.  
38.         DynamicGI.UpdateMaterials(renderer);
39.         DynamicGI.UpdateEnvironment();
40.     }
41. }

I believe you just have to set your emissionValue to 0 :

1. 
   
   Code (CSharp):

   1. DynamicGI.SetEmissive(renderer, (someArbitraryColor * 0));

 

I was able to turn them on and off by just setting the color. But what I was really after was the emission value. Are you able modify it in runtime? Or does your code get to it through the color?

Code (CSharp):

1.     void Awake()
2.     {
3.         renderer = GetComponent<Renderer>();
4.         material = renderer.sharedMaterial;
5.     }
6.  
7.     public void ToggleLights()
8.     {
9.         isOn = !isOn;
10.  
11.         if (!isOn)
12.         {  
13.             DynamicGI.SetEmissive(renderer, black);
14.         }
15.         else
16.         {
17.             DynamicGI.SetEmissive(renderer, white);
18.         }
19.       }
20.     }

 

Sorry for getting back this late.
You just have to multiply the intensity color by the desired emission value.

Code (CSharp):

1.  
2.  
3.         float desiredIntensity = 5f;
4.  
5.         void Awake()
6.         {
7.             renderer = GetComponent<Renderer>();
8.             material = renderer.sharedMaterial;
9.         }
10.    
11.         public void ToggleLights()
12.         {
13.             isOn = !isOn;
14.    
15.             if (!isOn)
16.             {
17.                 DynamicGI.SetEmissive(renderer, black * 0);
18.             }
19.             else
20.             {
21.                 DynamicGI.SetEmissive(renderer, white * desiredIntensity);
22.             }
23.           }
24.         }
