Blurred background without DFrame

[MyDimeIsUp]

Title says it all,

How do I make a certain part blurred? For something like a hud, Say I only blur the background of a box for a HUD. Any idea?

Thanks

Theres an Lua snippet out there, that allows you to draw an blurred box, and then draw over it, I dont know if I am allowed to post it here, but I'll do that:

local blur = Material("pp/blurscreen")
function draw.Blur(x, y, w, h, layers, density, alpha)
	local X, Y = 0,0
	local scrW, scrH = ScrW(), ScrH()

	surface.SetDrawColor(255, 255, 255, alpha)
	surface.SetMaterial(blur)

	for i = 1, 3 do
		blur:SetFloat("$blur", (i / layers) * density)
		blur:Recompute()

		render.UpdateScreenEffectTexture()

		render.SetScissorRect(x, y, x+w, y+h, true)
			surface.DrawTexturedRect(X * -1, Y * -1, scrW, scrH)
		render.SetScissorRect(0, 0, 0, 0, false)
	end
end

to use it, draw the blur box, and then draw something over it(the normal box should have an alpha of 200 or lower for good effect).

Thanks whitestar!
