Spotlight with scripted attributes breaks VRayLightLister

[Art48]

Hi,

I made a script to create a sort of "advanced" SpotLight which includes a while sphere at the end of it to simulate a real geometry which can get reflected in surfaces etc, basically to fake the "affect reflections" checkbox of the normal VRayLights.
It includes a custom attribute under a new rollout in the light itself. Now it seems the VRayLightLister doesn't handle this well and crashes. Max file, and script attached.
As soon as I remove the custom attributes from said script and the light itself is 100% standard with no additions, it works.

Please note the attached max file was created with the section in the script responsible for the custom attribute commented out, so it works.
If you run the script with the attributes section uncommented, the error occurs as soon as you open the lightLister after having created the light by the script.

Hello,

During the controls construction in the light lister there is a function to that obtains the values of the properties:

fn getLightProp obj prop =
(
if (isProperty obj prop) and not (isProperty obj #delegate) then
getProperty obj prop
else
if isProperty obj #delegate then
if isProperty obj.delegate prop then
getProperty obj.delegate prop
else undefined
else undefined
)


and when the custom properties rollout is added the second expression fails. This actually breaks the standard LightLister as well. I guess it would have worked for scripted plugins that extend the class, but in this case obj.delegate is a valid property that equals to undefined.

I couldn't find way around it so far.

Best regards,
Alexander

Hi,
thanks for the reply. What would you suggest to make it work? Extending the class? SOrry I am not toooo experienced with that plugin stuff
