HEEELPPPP !!! LIGHTCACHE PASS SOMETIMES RENDER IN BLACK

[lrivero]

hi

i have a large and complex scene with around 4 million polygons and with around 150 trees instanced from 20 models of vrayproxies... a few ground objects with displacement and only one light... it's an exterior light

every of these trees are excluded from gen and rec GI

but the strange point is that the render starts and when the "building light chace" arrives...... some times IN THE SAME NODE OF THE RENDER FARM goes perfect and other times the "building cache pass" goes very fast and appears in black... irradiance map too and the render is totally black

these are the images i am getting ...

another specs for you

render farm is with windows advanced server 2003
20xdual 3.02Ghz XEON with 2Gb

another servers are
2xdual 2Ghz with4Gb

and these servers render the scene well double of times than the render farm

it seems to be very strange because restarting the job some times the same node goes well

maybe one of the computers isnt picking up the light-cache file?

[lrivero]

no, sorry each node is calculating its own litghcache since this is only a test of the scene and i don't have any file stored yet... because is failing

thanks for the idea

What version of vray are you using?
