I have tried looking up the help tutorial but it does not explain this feature?!

 

Thank again in advance

Quote

• Emissive controls how bright a material appears independent of the lighting in the scene. It can be used to simulate surfaces that are glowing with their own light, such as the screen on a tv, but does not actually contribute light to the scene except in GPU Ray Traced Physically Based and Clay renderings. Only available for General, Translucent, and Transparent materials, tThis option can also be edited via the Adjust Lights dialog, but is not available when Metallic is checked, above. See Adjust Area Light Material Dialog.
  • Choose a level of brightness from the drop-down list and customize it using the spin control arrows or text field.
• The Apply Emissive and Color from Light(s) setting applies when the selected material is an Area Light assigned to a Light Fixture. See Light Fixtures.
  • When this is box unchecked, the selected material uses the Emissive value set here and the Color set on the Pattern panel.
  • When this box is checked, the material instead uses the Intensity value and light Color assigned to each light object. Light Data Panel.

The key to finding the help is to click on the little button with the arrow next to the material class to expand the section.

I've always found this video on Material Properties to be easy to understand and a good overview.  

"Emissivity" is discussed at the 11:59 mark in the video.

It should be noted that specifically regarding the Emissive setting, the video is a little out of date.  In X16, that setting does indeed cast actual light on the scene in Physically Based (Ray Trace) views.

thanks that's great.. I've never used it but am trying to get as much realism into my ext/int  renderings as much as possible
