Hey guys,

I am rendering a model of mine in mental ray. I was looking at the option under the GI panel and noticed a check box for photon map rebuild. If i have no check mark in it, does that mean it wont recaculate my photons every frame as long as my model does not move. and also there is an option under the final gather tab as well like that. Is thatwhat those are for and if not what does that. Is there something that you can say dont recaculate if models dont move. thanks guys. peace

Yes it's right.
uncheck that option will force MR to re-use the photon map that has been calculated in the first frame. But i think you should type a name for the file where the map should be stored ( as i've tested of course because it's not mentioned or i've missed it).
good luck.
