which is the right method to work with vray?

[juan_max]

I want to know if the ussual way to work is storing the photons map, the light map, and the irradiance map, and after that do the render. if it is like this, how?, is necessary to render all the maps with the same resolution as the final render?, is possible to use the same light map or photon map or irradiance map for different renders with different cameras?
thanks.

you can render the lightmap/irmap in a res twice lower than the final res.
