I made a level in a project originally done in 4.4.3 , and I spent a lot of time ensuring I had good lighting maps done as separate UV channels for every asset… and in 4.4.3 it worked., it built with no errors at all… but now that 4.5.1 is out and I’m trying to move ahead with it… the copy I made when opening that level with the new release, won’t build ?
