I've added new turret models to an existing ship model in CFHODEd. It shows perfectly O.K. in that and when I load up the game, however when you move the camera, in certain angles the turret models become totally black. I've been through each LOD, hit "Re-material", hit "Re-normal" but nothing appears to work. I use Shader 2.0 for the record. Any ideas what's causing this and, more importantly, any ideas how I can fix this, please?
