Disappearing geometry

[Fabrice]

I render a lot of anim and regularely some pic are bad because portion of geometry are missing
It's as if a boolean substraction was done on all the objects in the middle of my scene !
if I render again the same pic the problem disappear

Someone has allready seen it ?
Have this problem since 1.09 + Max 5 (now on 1.46.14 + Max 7).
5 PCs on w2000pro

Yeah I had that too a few times, never figured out what the cause was...

[suurland]

Me too, especially when I render with fields. One field will be fine and the other will have pieces missing. Max 7/ Vray .13

I've gotten it too, pretty low percentage of frames but usually a few per animation job,with lots of frames and layers. Always a perfect rectangular boolean...

Hmm ok ditto here, I had shrugged it off as I thought there was an issue with my file or slaves but looks like its hapening elsewhere also

same for me
on all almost all network rendering i see that bug
it would be great that we can solve this
it is very annoying to verify all the frames of an animation

What is your scene scale in System units? How "large" are the missing parts in system units? Were the bad frames rendered on a dual processor and/or HT machine?

system units is cm
missing parts are size of a bucket
dual xeon with ht no diff without ht

Seems to be a quite popular bug.

All machines are HT bi-xeon 3.06 GHz XP pro SP1 with 2Go ECC.

Unis is 1mm, scenes sizes are about 10 to 90 m large.
Size of the chunk varies a lot from 2 cm to a quarter of the scene...

If any of you with this bug feels like experimenting, please send me an email to vlado@chaosgroup.com and we can work towards fixing this (meaning you will probably have to test several different VRay builds to see if there is any improvement or differences).

Best regards,
