How to set EmissionMap's color of HDRP/Decal during runtime

So, I'm trying to set HDRP/Decal EmissionMap's color to emission color during runtime.
I tried:
decalProjector.material.SetColor("_EMISSIVEMAP", targetColor);

P.s.:
1. I have to use EmissionMap instead of BaseColor since I have a PNG to show emission, and it only works if I put it under emissionMap.
2. This property keyword is the one I found under debug mode inspector. But it's not taken effect, really curious to what went wrong here.

 

Hi,
I think the keyword should be _EmissiveColor.
Instead of looking to those Shader Keywords, open the HDRP shader sources and check there.
i.e. in this case it should be Decal.shader file.

There you can see this:

Code (HLSL):

1. [ToggleUI] _Emissive("_Emissive", Range(0.0, 1.0)) = 0.0
2. [HDR] _EmissiveColor("EmissiveColor", Color) = (0, 0, 0)

Then just change it like you did.

Code (HLSL):

1. material.SetColor("_EmissiveColor", targetColor);

Just make sure your exposure or something else in the HDRP won't make the effect invisible.

 

Thx man, worked like a charm!

 

What is a "targetColor"? This is not working:

material.SetColor("_Color", Color.red);
