Lightmapping ignoring objects

Hi all,

I am attempting to light-map my scene in unity however it is ignoring a group of objects that I imported. All the objects have UVs. I am really not sure what information I should provide to solve this issue. Could someone point me in the correct direction?

Check this question for three different reasons why your lightmapping may not have worked/isn't working:

How do I get objects to cast shadows on each other using BEAST?

Also, please try looking around a bit before asking a question; it saves both you and us time.
