Lighting build error Please help

I am farly new to unreal engine. Everytime i try to build the lighting, i get this error message.

Please help

There is not enough information in that error, and it may be caused by many things.

Can you add some description about lightning you use?

I only use the standard light setup in the empty template: Skylight and a directional light. I don’t really know where to get more information, that’s the only error it seems to be giving me.

So you just created new map from template, build light in it and get this error?

When lightning build finished, it creates asset “map_BuildData”, and stores lightning information inside it. Maybe you accidentially delete it?

I used this template: Screenshot - 57617b449da26027bdd894583bd3d96c - Gyazo and made this: Screenshot - bf1b21bbd8d17fa440351fbd6ad80a0b - Gyazo
I could build the light in the start, but I don’t know what happened to make it so I can’t build the light anymore.

that could be it, can I readd it?

It will be added after next lightning build

But that’s what I am trying to do, and this is the error I get everytime: Screenshot - bf1749272ed617dab678ff82657a6d6e - Gyazo

Never mind, I managed to fix it. I just had to restart the computer :confused:
