Emissive not showing on primative in Surfaces tab
I'm trying to create light that comes off a cell phone screen. I used to use the youtube video by Rauko for emmisive lighting. But, in the surfaces tab, the option Emmisive is not the there, nor is it searchable.

1stly check what the shader that the selected surface uses ... on the top of the Surfaces pane > Editor tab. Is it Iray Uber (MDL) ?
Which shader does the surface have? Listed on top of the surface tab.
I'm not fiding that. I created a Primative plane so i can have emmisive light from it. When i click on the plane, then go to surfaces, I don't see anything about shaders.
Look at top-left of the Surfaces pane>Editor tab.
If its a primitive plane you will have to add an emmissive shader to it. Primitives don't really come with their own textures.
Check the screen shot down below... see if you can try setting the Emission to get the expected effect ~~
