So, I created a custom .NIF model for a mod I'm attempting - basically an expansion upon The Sink in OWB - but for some reason I can't select the object in the GECK except through a selection-box or through the object list, and I can't click-and-drag to move it (since the render window is treating it as if it were nonexistant). I've never encountered this problem before, especially with an object whose collision mesh works fine.
The .nif file is http://dl.dropbox.com/u/1657500/nvdlc03_sinkrmwallexsm01.nif. It was exported directly from Blender, with no post-exportation alterations - as far as I can tell, they aren't needed, but that might be the source of the problem, I suppose. I can't find any decent (and up-to-date) tutorials on the issue, though.
Any ideas why it would act this way?
