[Bf-committers] Camera is a Lamp ?

[Ton Roosendaal]

Hi,

The SHIFT+Z option calculates light as of it would be rendered pressing  
F12. That means always relative to the camera position. With points  
lying behind a camera results can seem unpredictable yes. Just  
subdivide the plane some, and rotate from camera view itself to see why  
it still looks good. BTW; it's the specularity playing tricks with you.
