My problem is, I've a finished Maxscript script and I 'd like to run in c# ...

It's create few model, and export that. It is possible?

Yes, I already saw that, but that was my first question, 

So, how can declare the 'global' parameter in here, what is the type:

string myNode = MaxScriptExecute("$myNode", global).ToNode; 

Yes, you 've right, I just don't interpreted your answer. Now that is work, but my other question, if I want to execute the script, I get a "NullReferenceException was unhandled" error.

Do you have any idea why?
