lightmapping completely dark

[topofsteel]

When I lightmap my scene, none of the lights are working. The lights and the meshes are both static. The mesh ‘scale in lightmap’ is set. The lights work in the scene when the lightmaps are off. I’m at a loss. It takes 4 hours to lightmap and i’ve tried a number of times. What can I try? Thanks.

I had the same problem yesterday. Mine is caused my object UV that share the same UV coordinate. I had to re-map all the object’s UV and problem solved. I’m not sure that your is caused by object UV like mind. I’m no where near beginner on modeling.
