Webcam Texture into the Emission

[Spookytooth3D]

I am working to get a Webcam Texture piped into the _EMISSION node of a default shader. I have created a custom material to take the input, but for some reason, it’s not working as expected.

I can get it to pipe into the mainTexture, just not into the Emission. Incidentally, I am using the mainTexture to take advantage of the alpha channel, so I don’t want the main channel as my webcamTexture. I can set all of this up and working using regular single texture maps, just wanting a live image in the Emission.

Here’s the code thus far…

#pragma strict
private var webcamTexture1 : WebCamTexture;
var plane1 : Transform;
var plane1 : Transform;
var myMaterial : Material;
function Start () {
webcamTexture1 = WebCamTexture();
var renderer: Renderer = GetComponent.();
var devices : WebCamDevice[ ] = WebCamTexture.devices;

if(devices.length > 1){
webcamTexture1.deviceName = devices[0].name;
myMaterial.EnableKeyword (“_EMISSION”);
myMaterial.SetTexture(“_EMISSION”, webcamTexture1);
webcamTexture1.Play();
}
}

Any help here is much appreciated.
Cheers!

Which shader are you using? (in standard shader the emission texture is “_EmissionMap”)

I am using a default material, but had not found the reference to “_EmissionMap”. That fixed it! Thank you!! I’ve cleaned up the code to help anyone else that might want to do the same thing. Cheers!

#pragma strict

private var webcamTexture1 : WebCamTexture;

var myMaterial : Material;

function Start () {

     webcamTexture1 = WebCamTexture();

     var devices : WebCamDevice[] = WebCamTexture.devices;
     if(devices.length > 1){
          webcamTexture1.deviceName = devices[0].name;

          myMaterial.EnableKeyword ("_EMISSION");
          myMaterial.SetTexture("_EmissionMap", webcamTexture1);

          webcamTexture1.Play();
     }
}

You can see shader details by right clicking over the shader or that small settings wheel, and do Select Shader

Then can see these

This is great! Nice tip!
Thank you for that… should save a ton of time!
