Hi, I don’t understand one thing…
If I calculate the GI map with this parameters:

with camera 1 (for example) selected, when I render the camera 3 (with the saved GI files), the GI is incorrect??
Why?
Do I need to calculate the GI map for all my camera??
or Is there a method to use the same saved files???
Thanks

irradiance mapping is camera (view) dependent.

photon mapping is view independent.

you can keep your photonmap file, but for a different view you have to rerender the irradiance map. Vlado had a great tutorial on using the incremental add option to do just this thing.
