Corona Light Select Element

[nicdan81]

Hello

I am new to Corona and I have an issue with Corona Light Select Element: it looks pretty much like the Beauty Element. It is nothing like the Vray Light Select which contains only the selected light so I can use it in post production in PS in Screen blending mode. Because in Corona the Light Select looks like the Beauty, using it in PS modifies the exposure of the whole image not only the desired light. What am I missing here? Thanks
