Target Render not working

[Jackthemaster]

I'm trying to do a Render Target scope for my weapon and every time I pull it out, it crashes the game.

Here is the code:

[lua] local matScreen = Material( "hunter/myplastic" )

local RTTexture = GetRenderTarget( "ScopeTest2", 256, 256 )

function SWEP:DrawHUD()

local NewRT = RTTexture
local oldW = ScrW()
local oldH = ScrH()

matScreen:SetMaterialTexture( "$basetexture", NewRT )

local OldRT = render.GetRenderTarget();

render.SetRenderTarget( NewRT )

render.SetViewPort( 0, 0, 256, 256 )

local pos = {}
pos.angles = LocalPlayer():EyeAngles()
pos.origin =LocalPlayer():GetShootPos()
pos.x = 0
pos.y = 0
pos.w = 256
pos.h = 256
pos.drawviewmodel = false
pos.fov = 5

render.RenderView( pos )

render.SetRenderTarget( OldRT )

render.SetViewPort( 0, 0, oldW, oldH )
end[/lua]

Anyone?
