'Lamp' material without using an actual light source

[Anonymous]

So I am trying to develop a way to cheat on our renders and keep render times down by cranking up gamma or dark/light multiplier to give good overall brightness without trying to illuminate scenes by supplying tonnes of light sources. However, it would be really good to make lights in a scene look like they're 'ON' even when they're not really. I thought I had cracked it when I read this....

However, seemingly duplicating the settings doesn't work and what's really baffling me is that the 'specular' layer is completely missing from surface settings in AC20? Has this option moved or been replaced by something else?

The Reflectance channel combines the Reflection and Specular channels of earlier versions.

Thanks. I have some reading to do to understand what I ought to change to get the effect I want but hopefully that guide should do it.

Yep. Me too. I don't even pretend to understand all of this, but still, it is so exciting.
