Hi Matthias : Thanks for this awesome shader and example project . It is over my head right now , but I do understand the reason you created it , and will master it shortly , and then make a little tutorial on how others can easily modify many lights in a scene .
As a sidenote , my tests show that we do not need to create a Lightsensitivity channel to use that 'LS' shader , but just need to apply that shader to the light in question , so is an easy way to adjust lighting for objects affected by that part- icular light , as was Arjo's situation . Your advanced project has that 'LS' shader added to the 'Root' of your example project for some reason , and if you explained why so above , I'm sorry , but I still do not under- stand why you added it there . Anyway , give me some time to get caught up on things and I will explore and then share my trip through hell ... err , I mean , my delightful time working with this new and wonderful material you have created (just kidding) .
