Attached is a render of the inside of a module I have created.
As you can see I have some lights using neon material with a high luminosity,
The backing plate behind the light has high reflectivity and high luminosity. However although the lights look lit, it isn't as if the light is spreading round the interior if you get my meaning.
I don't want to add a specific light source or is it the only way to light up the interior, or just increase luminosity of the wall panels and other items?
