Is there a way to know if a node exists without producing a log entry? Using

Code:

getNodeType( NodeHandle node )

and test for an invalid handle produces an error in the log.

Currently I can only propose you a workaround. You could decrease the message level (EngineOptions::MaxLogLevel) and use the getNodeType function after that. Probably it would make sense to add a special function for validating a node/resource handle.

Wouldn't using findNode work as well? As it would return a 0 if it can't find the node you're looking for.. granted you'd need to know it's string and resource type, but it's better than nothing

I am really having a hard time coming up with a reason to do this - any chance you could explain yours?
