How the emission take effect in meta pass?

I write my own meta pass and seems the emission filed does not take effect. I select the Emissive mode in scene view after the bake finish, but can not see any color. And I assign a very large value to the emission field seems no any affect to the lightingmap.

Code (CSharp):

1.  
2. MetaInput metaInput;
3. metaInput.Albedo = brdfData.diffuse + brdfData.specular * brdfData.roughness * 0.5;
4. metaInput.SpecularColor = half3(0, 0, 0);
5. metaInput.Emission = surfaceData.emission;
6.  
7. return MetaFragment(metaInput);
8.  

 

@KEngelstoft , does you mean I add this in my shader GUI:

Code (CSharp):

1. materialEditor.LightmapEmissionProperty();

And I set it to baked:


And I just mock my meta pass to make sure the Emission is a large red value:

Code (CSharp):

1.  
2. MetaInput metaInput;
3. metaInput.Albedo = brdfData.diffuse + brdfData.specular * brdfData.roughness * 0.5;
4. metaInput.SpecularColor = half3(0, 0, 0);
5. metaInput.Emission = half3(100, 0, 0);// surfaceData.emission;
6.  

And I re-bake my test scene:

 

I find just to the <code>materialEditor.LightmapEmissionProperty();</code> and select it to bake is not enough.
I have to disable the EmissivelesBlack at the same time.
In the debug view of the inspector, I change the lightmap flag from 4 to 2, and everything is OK.

BTW, is there a way I can modify this flag without a custom shader GUI?

 

I think I'm having a similar problem, I know this is a year old, but could you elaborate a little bit more on your solution, I don't get it.

 

The directly method is change the inspector into debug mode, then you can tweak any internal properties. What I do is select the material want to emissive light, and change it's 'lightmap flag' into value '2'.
Or you can write a custom shader GUI editor to do this.
