Am I drawing an invisible spheres ?

[Zignd]

I'm trying to draw spheres, so I did the following:

if CLIENT then
	local positions = {}

        // here the table positions is filled...

	hook.Add("PostDrawOpaqueRenderables", "sphere_draw", function(b1, b2)
                print("Drawing...")
		for i = 1, #positions do
			render.DrawSphere(positions[i], 500, 1, 1, {76, 181, 108, 50})
		end
	end)
end

The problem is that it's not working, I also get no errors and I'm sure the code is being executed because the print("Drawing...") fills my console.

Can someone help me please? I think the problem might be with the HOOK I'm using, but I'm not sure which one should I use to draw it.

Thanks in advance.

You gotta set the material beforehand, and use proper color structure instead of that table.

Also it did not worked, nothing changed, although you were right it requires a Color table not a simple table, thanks for that.

Look, I added the Color table as you said, but it still does not work, also you said that I had to set the material, could you please explain how can I do that, none of the parameters of the render.DrawSphere function specify such thing.

if CLIENT then
	local positions = {}

       // table gets filled here...

	hook.Add("PostDrawOpaqueRenderables", "positions_draw", function(b1, b2)
		for i = 1, #positions do
			render.DrawSphere(positions[i], 500, 50, 50, Color(76, 181, 108, 50))
		end
	end)
end

Come on, can someone help me please?

//Outside of the hook
local arrow = Material("widgets/arrow.png", "nocull")

for i = 1, #positions do
render.SetMaterial( arrow )
render.DrawSphere(positions[i], 500, 1, 1, Color(76, 181, 108, 50))
end
