[Closed] How to check/uncheck Render Elements vrayVFB

re = maxOps.GetRenderElementMgr #Production
for i = 0 to (re.numrenderelements())-1 do
(
	local rel = re.getrenderelement i
	if (rel != undefined and classof rel == VRayNormals) then
		if hasProperty rel #vrayVFB then rel.vrayVFB = false
)

Thank you.
I thought that properties of vray is separate.
