So basically, Im using an Asset from the asset store for my corridors, I dont wanted to use one asset for everything, so I build me up one corridor and created a Static mesh of it, and made up the collison, but after building the lights in Production quality, The lights kinda messed up, and only those where I do use the orginal assets are working fine, and I think I know the Problem, Its because of the UV MAPS… (probably) but I dont really know how to fix it.
