photon map question 2004-04-13 - By Bernard Lebel
Back
Actually if you put the photon map on the C drive (each machine having a C
drive), each machine will compute its own. As far as continuity goes I'm not
sure it will work perfectly, but you should give it a go.
Cheers

the obvious approach, given that it changes from frame to frame. However,
the thing is that if I render through our rendering pipeline, the PhotonMap
gets written in one central location, not on the individual render node, so
you end up having, say, 20 instances of mental ray trying to write
'PhotonMap' or whatever the file name in the same location, which obviously
causes all kinds of trouble. So, if each frame had a different photon map
filename, this would be a non-issue. The other approach would be to get MR
to generate the photon map locally on the render machine... I'll look into
that as well.
