Light Path Expression Get and SetAttr

[Tyros]

Hi,

I am trying to create an automated script to generate light selects with specific light expressions.

Two inputs
Filename Suffix - NAME A
and
Inside the Light Select, When We change Type = Light Path Expression.

The field "Light Path Expression" become available.

Is there a way I can have a setAttr or getAttr for this input? What would be the proper command? I prefer in python, but can be in mel too.

I did try check full verbosity but the script editor gives me a lot information, maybe someone could help me figure out the correct Get and Set Attribute for the input.

script editor give me like

setAttr -type "string" vrayRE_Light_Select8.vray_lpe_lightselect `textField -q -tx AttributeEditor|MainAttributeEditorLayout|formLayo ut101|AErootLayout|AEStackLayout|AErootLayoutPane| AEbaseFormLayout|AEcontrolFormLayout|AttrEdVRayRen derElementSetFormLayout|scrollLayout4|columnLayout 168|AllExtraAttributes|frameLayout93|vrayAEMasterC olumnLayout|vrayLightSelectChannel_VRayRenderEleme ntSet|vray_lpe_lightselect_VRayRenderElementSet_ro w|vray_lpe_lightselect_VRayRenderElementSet`;

but maybe there is a simpler key word to set and get this attribute, for these inputs?

Filename suffix
and
Light Path Expression

Image attached for the input I would love to have

Thanks in advance

Hi there
You would need just the first part of what is returned to you in the script editor, which would be setAttr -type "string" vrayRE_Light_Select8.vray_lpe_lightselect "Name A"

For mel if you'll need to create multiple LPEs you can try this and see if it works for you:
$l = `vrayAddRenderElement LightSelectElement`;
setAttr ($l+".vray_name_lightselect") -type "string" "Name_A";
setAttr ($l+".vray_type_lightselect") 9;
setAttr ($l+".vray_lpe_lightselect") -type "string" "C.*L";
