Propper, Propper, Propper .31

[DJBREIT]

I was debiting whether this should go here or in the Modeling form. But since propper.exe works with hammer I decided to post here. Unless an administrator thinks other wise. (Sorry I was on the modeling form when I hit post)
I have been playing around with Propper v.31 for the last couple of months. Most of it was static props. But I wanted to start using some of the other things that was mentioned on the steam form.

First is there anyone working on a newer version of Propper.exe

These I cannot find in Hammer/Propper
Propper_attachment
Propper_cables
Propper_particles
Propper_physgun_interactions
Propper_gibs
Propper_bodygroup

This one, Not too sure on how this is used
Propper_lod

I also have found that my Propper models don’t like to cast shadows?
An is there a way to give models properties like the chain link fence hl2 or is this something you have to do out side propper?
