Been a long time lurking, decided to join to making tracking/watching mods, and indie games far easier on myself.
Now, this taught me afew things.
First of all; stick to 128.8 for the height, it just, looks so much better. Also, they will actually attack NPCs, thought that was strange myself.
Physics Objects are required for some of the Props, took me ages to figure that one out (and some, rabid webcrawler-foo).
Hopefully this is a good start, and I intend to keep working on my mapping skills, as I go.
