I just updated my Houdini Master license but when I tried to use the wavefront converter, it says that I need a license, what give?

My Houdini Master is working just fine.

It might be require a full houdini license. Are you running houdini at the same time when you're trying this? If so, try quitting houdini and then running gwavefront.

Ok, i'm not at home (I'll check later) but if your using the NC versions (you didn't specify) and gwwavefront is one of the apps installed with houidini setup, each of them requires a seperate license (as if each was bought and installed separately); even though i use houdini master NC almost exclusively, I have used some of the other apps (halo, etc) and they each ask for separate licenses upon first use. If this isn't your situation, forgive my presumption….I just know this is how it is with the NC stuff…
