Hi, Thanks for raising this issue. I've just tested with version 5.3.2 and everything seems to work as expected. I'll download the latest Unity version and see if I can reproduce the problems you're experiencing. EDIT: After re-reading your post, I better understand the issue you're describing. In the example scene the Player Info script (which uses the LOS Visibility Info component) checks the tag of the LOS source and makes sure the players own LOS sources are excluded. For now it's the responsibility of the script using the LOS Visibility Info events, or list of visible sources, to exclude the LOS sources which are invalid. It was designed as generic as possible, so that it could be used in a number of different situations and projects. I could add extra functionality that would ignore objects on layers which are set as invisible to the LOS source camera using the Culling mask property.
