Issue with blockcasting with smooth mesh player

[Planteron (Son Goku)]

I want to shoot a blockcast from the character, but for some reason, it doesn’t blacklist the custom character I’m using. The character is a smooth mesh btw
This is the code I have:

RemoteEvent.OnServerEvent:Connect(function(player)
	local character = player.Character
	local root = character:FindFirstChild('HumanoidRootPart')
	local rp = RaycastParams.new()
	rp.FilterType = Enum.RaycastFilterType.Exclude
	rp.FilterDescendantsInstances = {character:GetChildren()}

	local hitRay = workspace:Blockcast(root.CFrame, root.Size, root.CFrame.LookVector * 3)
	if hitRay then
		if hitRay.Instance then
			print(hitRay.Instance)
			print(hitRay.Instance.Parent)
		end
	end
end)

this is a screenshot of it

also in the table I already tried using the normal character in the table and not character:GetChildren() and for some reason it works just fine with regular r6

You’re not using the RaycastParams in the actual Blockcast.
