I've been playing with PV360 for the first time and I've hit my first problem - basically I'm rendering an assembly that has an open and closed configuration, but this is done with a 2nd instance of the same part due to using an horizontal style build process. When I hide the 1st instances of the parts to render the 2nd instances they dont show up in PV360. Is there something I need to know? I dont want to have to create separate assemblies to use the program....

Thanks
