Ohh sorry, shoulda spoken up about it being a TF2 mod, I thought it was a given being I posted about it in a TF2 thread.
I kinda like that you can't change your model when you're on the prop side, kind of makes the whole process a lot more fun to hide.
There was one time where I was on a map with a setting similar to the Valve map Egypt, and I was turned into a palm tree. Now normally I'd be really upset about this, but I ended up being the final member on my team to survive, all I did was go to an area with scattered palm trees and set myself down in an area properly spaced out from the rest where a tree looked like it could be. I was totally hiding in plain sight, and it worked for the longest time.
If I could change what prop I was it'd be just too easy to want to be the small object every time and never be forced to find interesting spots.
