Hi,
I’ve been having this problem at my job where I need to go through a scene’s objects and check if they have a custom attribute on them. Whenever you try to access one of the C.A properties of an object that has no C.A applied , it returns an error.

Thus the solution for now is to do a try()catch(). But on a large group of objects , the UI (dotnet) becomes slow because of that check. When I did put that checkup part under comments,
the process was much faster.

So the question is: Is there a way to ask to an object if it has been assigned with a specified custom attribute. Returning a true / false , an empty list or whatever! As long as it’s not an error!

Thanks in advance!

custAttributes.count <obj> [baseObject:<bool>] maybe?

Also can test for concrete property using isProperty() function

I believe isProperty is just a wrapper for try/catch, it takes the same amount of time to execute as try/catch if the result is false.
