Hello, sorry if that’s wrong place for asking, but i didn’t see any better one.
I’m making my first game, i already did some closed spaces in it, and now i decided that the lights there should be more intense. So i would like to change all lights intensity without regrouping and clicking it around for an hour. Is there a way i can select them all (i know it is) and change intensity of all of them at once (can’t find it)?
Thank you for spending time reading my bad english 
And once again, hello everyone 
I will write here from time to time, not always with troubles xD
EDIT: Not actual. I found a soulution.
