Hey lightning!
I have a few question regarding your models.
1. Maybe this has already been fixed, but in some of your TGOs, I found shaders that didn't do anything. I even found a MOLA-map shader once.
2. Do you have a homepage or something I can link to? The pdf that comes with the free models says you want to be credited, but when I just write "lightning", few people will actually know who this "lightning" is.
