Wish: 255 white "light" materials

It would be very helpful if there was a way for materials to appear like "lights" by shading them as 255 255 255 white. I'm not asking for them to actually cast light, just appear self illuminated. 

One way this could be done is via material name. For instance - what if you enabled some material name overrides that when Prospect encounters them shades them in a special way. For instance - maybe any material with the text "ProspectLight" would be overriden in Prospect to appears as a light.

  Hi Chris, thanks for this feedback. Do you think there's ever a situation where you'd want the self-illuminated materials to be something other than white? We're thinking that one solution would be to have the "ProspectLight" material name work for any material regardless of color, and it would change the shader to emissive: https://docs.unity3d.com/Manual/StandardShaderMaterialParameterEmission.html

  Your suggestion Shane would definitely be preferred as it's more flexible and a great long term solution. I was simplifying it to "white" in an effort to expedite it but flexibility always wins for me.

  Hey,
  Have you already got the emissive materials to work and how about mirrors? I was searching a tutorial for them, but couldn't find any.

  For Sketchup, I suggest using just the "Emissive" keyword like Enscape does so that the model for Enscape also works for Iris.

  For Revit, there is a material property for emissivity.

  Indeed, there are other emissive color than white. For example: a computer scree with an image or a colored enclosed lamp shade. Signage models are often emissive.
