I have a scene within a sky sphere. There are a ship and some static meshes in the sphere.
Now I added some new objects by using the BSP box brush.
In the preview I can see the box is lit (shown in the following screenshot):
But as soon as I build the lighting and start the game the box is unlit.
In my scene I use a directional light and a skylight. Both are activated.
Furthermore I have a lighting error, because my sky sphere has wrapping UVs. But I suppose the unlit box is independent of this error?
Anyone have an idea what could cause this issue?
Thanks in advance.
