Why is this making everything black?

[TheTechPony]

	hook.Add("RenderScreenspaceEffects", "DrawMonsters", function()
		ChamsMat = CreateMaterial("Material", "VertexLitGeneric", { ["$basetexture"] = "models/debug/debugwhite", ["$model"] = 1, ["$ignorez"] = 1 })
		for k,v in pairs(player.GetAll()) do
			if v != LocalPlayer() and (1000 == 0 or v:GetPos():Distance(LocalPlayer():GetPos()) < 1000) and table.HasValue(Monsters, v) then
				cam.Start3D(EyePos(), EyeAngles())
					if (v:IsPlayer() and v:Alive() and v:Team() != TEAM_SPECTATOR) then
						if v:IsPlayer() then
							color = team.GetColor(v:Team())
						end
						render.SuppressEngineLighting(true)
						render.SetColorModulation(color.r/255, color.g/255, color.b/255, 1)
						render.MaterialOverride(ChamsMat)
						v:DrawModel()
						
						render.SetColorModulation((color.r + 150)/250, (color.g + 150)/250, (color.b + 150)/255, 1)						
					end
				cam.End3D()
			end
		end
	end)

I ripped this from aHack and plan to use it in my server so players can see certain players through walls but as soon as the hook runs all entities turn black even if I remove the hook/join another server. Any way I can make it not do that?
(The table is established earlier in the code)

[del]Let me guess, are you running under sandbox?

or at the very least a sandbox derived gamemode?[/del]

whoops, ignore that. I thought you were using stencils.

Thanks a ton!
