Default Re: FG Saving. How often?

other things to consider,

If a fg sample exists then it will be skipped when further FG samples are calculated, such as if you are doing a solar study and the camera is static, then FG will only be saved for the first frame and skiped for the rest. Solution, move the camera

Sometimes if you calculate too many frames you can run into problems running out of memeory when reloading the solution. 64bit doesn't have this issue

To save time and memory, us Photons and FG. Photons are not view dependant so only need to be calculated once. You only need the FG to "clean up" the photon solution so only the first bounce of FG is used so leave it a 0 bounce. Also very low FG settings work better.
