Garbage lights

I don't understand exactly why, but my dynamic lights rarely show up and if it does it appears as a hexagonal shape. but stretch. It's difficult to describe. But the dynamic lights are display nicely. What might be some reasons for this type of problem to occur?

Sounds like the mesh is too wide for the lights to catch properly. I think you can adjust some parameters in the advance tab of the build process to enable better dynamic lights but this is usually at the expense of build time. The results show good improvements though but not as good as a tighter networked mesh structure.
This then means LOD for close camera dynamic light effects if the structure isnt too large I think.
