stop at 0%

When I build lighting it end up stop at 0%. I don’t understand the problem of failed. what do i need to do? Is it better to invisible all particles b4 build lighting?

It’s likely that you don’t have anything in the scene to build lightmaps for. Disabling particles will make no difference to the lighting build.

Have you checked world settings to make sure that Force No Precomputed Lighting is unchecked?
