I would recommend for the blurring, looking up how to make motion blur, if you want to be able to see the body youll need to change the LocalTransparencyModifier property
yes but that blur seems kind of different its not like a blur but yeah idk how to explain that. This thing was also used in the “HeadOn - Body Cam Shooter Game”
Hmm yes I can see that now, I dont think there is much way to get it exactly like that, you could probably try goofing around with some kind of Gui, like a billboard gui and try to create a similar effect, how to do that I wouldnt know, but it may be possible
