I have a TP4 node in my scene which has a huge Group hierarchy. I get this error the moment I open krakatoa UI
Thx
It would be very helpful if you could post everything printed to the MAXScript Listener after the crash.
I want to see the variable states, although it appears that some property called “” has sneaked into the hierarchy of TP.
I haven’t seen this before, so there must be something special about this TP node. All I could do would be to ensure any property access happens in a try()catch() context to avoid the problem.
You could put a try()catch() around the “where” expression yourself.
for g in getPropNames theParent where (try(classof (getProperty theParent g)) == PGroup)catch(false)) do …
Here is the listener errors

Thx for the quick reply
Oh Cebas! 
As you can see, the variable g which contains the properties of an object as returned by getPropNames() contains a property called #. So the name of the property is “”, which is of course completely invalid. Since TP does not expose any real MAXScript methods for working with its properties, I had to hack this together to find out the groups and whether they are renderable or not.
I would expect that adding try()catch() as I explained in my previous post would solve this. Please modify your KrakatoaGUI.ms at the error location and see if it makes it work.
I will modify it on our side in about two hours.
Here is the updated KrakatoaGUI.ms file. Copy the content of the ZIP into your Krakatoa installation’s \Scripts folder.
(typically located under c:\Program Files\Frantic Films\Krakatoa\Scripts\ or c:\Program Files(x86)\Frantic Films\Krakatoa\Scripts\ on 64 bit OS)
Then please let me know if it solves the problem or not.
