I'm not aware of anyone being able to open 3D files of Raven Software's game Necrodome (1997). However, RaVeN-05 managed to export textures and sprites. All 3D models from Necro are super primitive, so I recreated them using Blender. More to come, there is about 7 vehicles left to do and loads of props, some of which I have not yet recognized where are they in game.
