I am building a level in 4.12. All was good and it has been up and running perfectly.
I went to modify the lights and now i am getting issues. Everything looks fine in editor, the second I build to my Device, all the lights turn off. Before this i have packaged the project without an issue and the lights were fine…
And i cannot for the life of me figure it out…I have not changed anything in my level other than adding and modifying location of the lights.
You need to re-build your levels lighting as it is broken. This happened when you added / moved your current lights. If you look at the top of your 2nd screenshot you can see a red message that says(I think as I can not read it very well) lighting needs to be re-built. Just you know, each time you do something to a light, unless you are using fully dynamic lights, you will need to re-build your levels lighting or things will turn out black. You can read more about this using the following link.
Thanks, i guess that opens another issue… i am starting to get that message no matter what. I always build before i package and no matter what that error pops up.
