Bake lighting on multiple copies of a room in the scene at the same time
Hi, I am creating a game environment which requires damaged versions of certain rooms in a house, because of the type of damage certain walls have collapsed revealing the walls internal structures, there are three versions of the room (undamaged, moderately damaged, extremely damaged) at runtime we will switch on/off the rooms so they become more damaged to the player when certain events happen such as explosions/fire etc.
What I need is to lightmap the whole house at once with all three versions of the rooms visible so they all receive the correct lighting from the other neighbouring rooms, but I don't want the three damaged versions of the rooms to cast light and shadow onto each other.
Is there any existing way to accomplish this using layers or groups, we are currently using bakery in our project.
