If you select the mesh you wish to export, and then you go to attributes. (The little A that comes up at the side of the model when it is higlighted) Once in attributes... sorry I am at work so have to work from memory ... use CTRL-D (or ALT-D if. Like I say I am working from memory) this will bring up an export box. Good luck. If you have any problems let me know and I will send through the info.
