[error] Light build

[pierpa86]

I create a box and a light point, after pressing Build Light, all the lights turn off with this error, pls help

[majic12]

Does the light build finish or does the message box opens right away?If you are using lightmass than you need to create a lightmass importance volume for the level or it will bake for a long time.Those errors have nothing to do with the situation you explain.
Some specs(os,gpu,cpu)
