Self Illuminated Texture - how to?

[neoRiley]

We have a scene that we've baked shadows / lighting into the textures, how do we create a "Self Illuminated" texture so that the babylon lights don't affect these textures?

 

I've created a StandardMaterial, set ambient and diffuse colors to white and that didn't create the effect I'm after:

var mat = new BABYLON.StandardMaterial(meshes[i].name, this.scene);mat.diffuseTexture = new BABYLON.Texture("meshes/demoRoom/textures/Room_COLOR.png", this.scene);mat.specularColor = new BABYLON.Color3(0, 0, 0);mat.ambientColor = new BABYLON.Color3(1, 1, 1);mat.diffuseColor = new BABYLON.Color3(1, 1, 1);

I added a hemisphere light with all there colors set to white and that worked to illuminate the room textures, but of course, that's not what we want for other elements in the scene.

 

I guess I could create a completely different scene for elements that are lit with real lights and another for elements that have baked materials, but it would be much more efficient if there were a material type for "self illuminated".

 

Thoughts?

 

Thanks guys

I'm not sure that will work, but have you tried to set an emissiveColor ?

 

Edit: 

I've just found that StandardMaterial has a property called emissiveTexture, you could try it

Setting emissiveColor worked just fine  I was thinking diffuseColor and ambient would have taken care of it, but this works

 

Thanks very much,

mat.emissiveColor = new BABYLON.Color3(1,1,1);

Is there a way to control the strength or power of emissiveTexture/Color?  In Blender you can set value on texture Influence - Emit..

[babbleon]

not that I know of, but:

mat.emissiveColor = new BABYLON.Color3(0.5,0.5,0.5);

...would reduce the strength.

However, PBRMaterial has emissiveIntensity.

Yes, with Color3 was pretty intuitive, I was looking for same thing with texture on StandardMaterial, but I guess for some good reasons it doesnt hold emissiveIntensity, I'll go with PBR then, thnx ppl!
