does it appear in the outliner? If so then try applying a shader to it. Other then that all I can say is although alias/wavefront created obj and they also created maya. I find maya to be one of the worst applications to import objs from other apps into. The Object is visible in the Outliner. If I select it, and press "F" for focus, i can see the Wireframe for a second, but then it disappears. I've converted the .stl into .obj in a Program called "MeshLab". In MeshLab, the .stl and the .obj are visible. Thats not my First Time, working with this workflow, but it's the first time I have to deal with this problem. I don't think tha, assigning an Object will fix this Problem, because I am able to see the Object in other Programs, and as far as i know, there's only the Wireframe visible if there's no Material assigned to the Object. I am going to check this tomorrow at work, but i'm not very confident that this would fix the Problem. Regards ZueB
