Scaling ragdolls?

[Tingle1989]

Hi, I've been trying to scale the ragdoll the player drops on death for a while now - and just cant get it to work.

This is what I'm doing:

    function Derp.PlayerDeath( ply )
            local scale = 0.5
            ply:GetRagdollEntity():SetModelScale( scale, 0 )
    end
    hook.Add("PlayerDeath", "Derp.PlayerDeath", Derp.PlayerDeath)

And also, Is it possible to somehow shrink the third person physgun effect, scale particles, decals and shadows?

Any ideas?
