Could be possible use only photon mapping in first and secondary bounces? (in order to calculate only one time the photon map an reuse it in all frames of an animation with camera movement), or quality with this map isn’t enough to forget irradiance map. :?:
Regards
(Sorry for my english)
yes…photon map is what u need… 8)
the quality will never be good enough to really use photon mapping for both bounces.
true that…but if u set the settings high enough…it would be ok…but take a long time to compute…chek this out..think should help a bit…

btw…under what situation.. u should u use photon map…and when u should not??? 
Marina,para usar en un render solo fotones (first y secondary bounces) tendrias q lanzar muchisimos d ellos y los tiempos suben mucho mucho
Usa fotones en los rebotes secundarios y guarda el mapa q sirve para todos los frames (es independiente d la vista d camara)

Thanks to all people for your responses. I’m seeing a little bit clearer now. I’ll ese irradiance for first bounce and photons for secondary. Regards
Didjaja, no se por qué, pero tu inglés lo entiendo mucho mejor que el de los demás
