Global illum (2)

[moss]

Hi,

I read that in global illumination 'rebuild photon map' is used in conjunction with a photon map but it didn't say how. If I render 1 frame with it checked and with a file name for 'photon map' wil that save a photon map? How do I reuse this map to save render time (what do I uncheck)?

Yes, if you render one frame after entering a file name for a photon map with 'rebuild photon map' checked, you can then uncheck this option for subsequent renders and the named photon map will be used. If you make any adjustments to your fg settings you will have to rebuild the photon map again (re-check this option and render one frame).

Cheers,
