Troubles.

Last week I was on midterm break and didn't do much work. But the little I did brought me to a dead end. For some reason I can't build the lighting in my level and I don't know why. I've been trying to find out what is causing the problem without success, specially because it's taking more or less 10 minutes to build the lighting in the level.

I think it is one of the static meshes I have imported recently, but I can't find which one yet. Other than that I still have a few things to adjust and after that I will be mostly doing programming.
