Hi,
when data for photons and/or media can NOT be safle loaded ?
I ques that camera moving/rotation is alwys safe, and any other changes is 
scene (objects or lights) is not safe - is this correct ?

Probably moving object that do not interact with photons is safe, but what 
if that object are in path beetwen two interacting object (and should block 
photons) ?

Moving lights that do not interact with fotons is alsow sefe ?

Moving the camera is always safe.  Moving lights that do not cast photons is
always safe.  Moving objects that do not have photons shot at them, that do
not recieve photons, and would not recieve photons in the new location is
always safe.  Moving an object that recieves photons to a new location where
it does not recieve photons is sometimes safe.  Moving an object to a
location where it recieves photons, moving an object that has photons shot
at it, or moving a light that casts photons is not safe.

Changing the texture of an object that recieves photons is safe.  Changing
the texture of an object that has photons shot at it produces results that
are not realistic, but can be useful sometimes.
