I have added collision meshes to almost all the assets in the world right now and re-exported them as .fbx files.  I just have a few trees and the weird, random tombstone left.  The collision system definitely needs more work.  It does generally function the way I want it to, but unfortunately it hangs in a few spots and doesn’t like complicated geometry at the moment.  I’m not going to let that keep me from releasing a version, though.  I’ll get the last assets fixed tonight then do a release.  After that I’ll need to make a list of improvements for the next release, so stay tuned.
