PONY, the version im speaking of came with lightwave, a handly featurew it actually made a render(like mayas default renderer) but(i assume others have done this) you sometimes try and scroll or tumble around your render to see other parts... then realize you cant.. well with this you can. And its all pre rendered. But say the light is coming from the left of where ever you render... And you spin 180 degrees around the object. It will look like you are moving, not the light or the object, because the same spots will always be highlighted. Same spots will have shadows. So the textures wont change at all.
