[RESOLVED] OVR_ASSERT fail in ovrHmd_ConfigureRendering()

You are passing osettings_.eyeFov into ovrHmd_ConfigureRendering without populating it. The FOV is an input parameter, not an output parameter, so you must initialize it. You can initialize it from either the DefaultEyeFov or the MaxEyeFov inside ovrHmd or you can manually set it up yourself (the smaller the FOV the less pixels you render, but you can't really change it dynamically at runtime).

Since you're note initializing it it probably has random memory in it, which means that the distortion function is trying to create a mesh for some absurd random value (or possibly 0) interpreted as an angle. The ASSERT is there to tell you the angle is absurd.
