Re: OpenGL gotchas !
I feel you 
Similar things that happened to me:
- backface culling is on, and the camera is *inside* the model.
- model is outside the clipping plane.
- model is *way* too big or too small (1 pixel is hard to spot on a blank HD screen)
- model has a fully transparent texture.
I'm sure there are more...
