MaxSceipt + Vraylight options

Здравствуйте. Возникла необходимость менять свойства группе Vraylight объектов.
Как- то так:

for i in selection do	if classOf i == VRayLight do try(i.doubleSided = boolean)catch()

Все бы хорошо, но с CastShadows такой номер не проходит.
ни так:

$.castShadows = off

ни так:

$.cast_Shadows = off

Помогите разобраться плз.

Поделюсь всем кодом. Может так смогу кого-нибудь заинтересовать. Помогите плз.
Небольшой скриптик умеет менять часть свойств всем выделенным камерам или ИС:

Узел (Node) VrayLight имеет свойство castShadows.
Базовый объект (baseObject) узла VrayLight тоже имеет свойство castShadows.
Свойство castShadows узла имеет преимущество перед свойством castShadows базового объекта узла.

Этот код меняет свойство castShadows узла:

$.castShadows=off

Этот код меняет свойство castShadows базового объекта узла:

$.baseObject.castShadows=off

класс! спасибо! Вот бы создать скриптик, наподобие light lister 3D Зверя, чтобы умел менять свойства не просто выделенному ИС, но всем выделенным + камеры...

кстати, как оцениваете перспективы python - как альтернативу maxscript'a???

Не надо дублировать вопрос в двух темах ! Модератор.
