Vray Object Properties get deleted

[CAPTURE_MM]

Hello,

I have a problem with my object properties getting deleted when "deleting unused nodes" from the hypershade
The properties are not empty and I just can prevent them from getting deleted when locking them manually via locknode command.
This just happens when I export the selected object/group/hierarchy together with the properties to a maya scene file and reimporting it to a new scene, but not if I delete unused nodes in the scene where the properties were created.

Build is: vray_adv_22501_maya2014_x64_22913 on maya 2013

I think I didn´t have this problem before.
Any ideas?
thanks in advance
greetings
andy

I've logged the issue in our tracker and we'll make sure to fix it.
Unfortunately, I cannot give you a timeframe, when this will happen.

Hi,
maybe now I know a bit more about the problem: if the property gets importet, it does not automaticly connect to the vraySettingsNode in the scene. maybe this is, why maya thinks it is unused... (although there are connections to its members... ?!)

There is an option in the Maya preferences whether to delete empty sets or not.
