Hi,

This should work:

(
	local re = maxOps.GetCurRenderElementMgr()
 
	for i = 0 to LayerManager.count - 1 do (
 
		local iLayer = LayerManager.getLayer i
		local layer = ILayerManager.getLayerObject iLayer.name
		local objs = refs.dependents layer
 
		local lgts = for o in objs where superclassof o == Light collect o
 
		if lgts.count > 0 do (
			local lsRE = VrayLightSelect elementname:("LightSelect_" + iLayer.name) lights:lgts
			re.AddRenderElement lsRE
		)
	)
)

Best,
Pixamoon
