Help with adding a texture shader please

Wilmap

I need to add a reflective strip to an item.

How can I do this in both 3Delight and Iray so that it glows in the dark, like those worn by firemen, etc?

I really have no idea about how to go about this.

I would create a black and white texture map, like you'd make for use as a transparency map, where the reflictive bits are white and the rest black. Then you could use it as a mask for Ambent settings and/or light emitting settings.

Thanks for that, I will give it a try.

 

Will that work for Iray as well?

Yes. Use the Iray Uber base shader, put the black and white map in the emission channel, and turn the emmision color to something other than black.
