I made my models in Wings3D (I dont use Blender to make my models).
But when I import models, the Blender show the scene without problems, but after I put a camera (and delete it in sequence) Blender always disappear with my models.
See this image:
If I use alt + 0 , ok, I see the scene, if I move mouse all objects disappear.
Someone can help me ?
Here the zip file with the same scene of screen.
