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
i was trying to eliminate some problems:::
A it’s not a problem related to cameras, i changed to perspective view, creating another acmera…
B it’s not totally asociated to lightcache, i tried with direct computation and irradiance
C it’s not a continuous trouble, sometimes the same node, render he frame 010, 050, and when it arrives to one frame such as 094 render the frame perfectly
another ADD to your knowledge about this trouble ::
i had computed lmap of one layer, the foreground, ( i’ve finally separated the scene in two parts the froeground and the midground) in one computer
and i have tried to launch the computing of irradiance map with the lightcache stored in a file… and again the first node i tried did the same… computing the imap in black and i restarted the job in another node ( with the same specs and partitions and pagefiles but "magic?? :lol: ) and it works and right now is computing imaps for that layer
i’ve finally found the trouble.. it was becuase a ground object made with edit poly that was cut and become corrupted
because this object was so simple as 300polies i always used it in every test i did and when the scene wasn’t with a lot of objects it didn’t do anything…
the question is why some times it appeared making the camera black??
ok, i am so glad finding this trouble that it doesn’t mind
