vray light select render element based on layer

By fed_86 · 2018-07-26

Description

would it be possible to have a script that does vray light select render elements based on layer?

let's say I have 5 layers in my scene, each one of them has few lights inside, I would like to have a script that select all the lights for each layer and create 5 vray light render elements

thank youu

We should use light colors to design and layout because they look attractive and on it we can show text clearly. Instead using other web use my assignment help it will show you design of layouts so that you can also make it.

Thank you for your help.

however for some reason it seems not working.. this is what I've got from maxscript listener after running the "code" you posted

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
