um, maybe I don't understand you. The problem I'm having is, UU won't even open a .dbo file. I created an object in DBPro, and saved it to file as .dbo. When I try to open that file in UU, it says unsupported file version, even though I have the DB plugin in the plugins directory. I know UU sees the plugin, because I have an option to load or save .dbo files. I haven't tried creating something in UU and exporting to .dbo, I'll try that right now, but I just wanted to see if I could bring in to UU a .dbo file, and I can't.
edit:
ok, if I create a primitive in UU, it will save it as a .dbo, but when I try to load itin DBPro, it crashes DBPro. I'm thinking the plugin is broken. I'm not sure if the UU guys support it or not, I'll send them an email.
