I've seen a couple other threads on this issue but I couldn't reply to them so here's another one. My light maps when rendered (iOS) are very very dark in the Editor & Game Windows. If I build the project, the light maps are used correctly when installed on the mobile devices. While this works, this is not an acceptable workaround. Its a terrible waste of time. Im very disappointed once again as it seems Unity is back to their push the releases out before major issues are finished. I thought they were going to slow down, which worked for awhile. I know Im not alone in this problem, this is a beta type issue, not a release problem. I watched this issue for 4 betas and it gets shipped. Wow, why did you release this? And yes, it doesn't matter what project I use to test this and with multiple computers. Back to 5.4, 5.5 gets trashed. Disappointed.
