More lightcache trouble

V-Ray V-Ray for 3ds Max V-Ray for 3ds Max :: General

Evening,

i’m having a lot of trouble with lightcache since I updated to vray 1.47.03,
first every object returning overbright color (see another thread in this section) and now, something I would have really liked to avoid, here are the facts :

I’m making an animation for tv, 16:9 format pal, 1024*576, all my camera pathes are made,I follow Vlado flythrough turotial, when making the lightcache flythrough calculation, max keeps crashing somewhere around 75% ofthe calculation process when subd are high,

500 gives me no crash, above 1000 makes max crash (stupid windows error “max encountered a problem and will now shutdown”)

Subd 2500 // fixed, world, prefilter 10, sample size .02cm

Is what makes max crashes

Same but with subd 1100 is ok…

Memory problem ? Running a p4 3.4HT with 2gig of ram on board.

Thanks for info in advance as deadline is, well hum bouh :shock: friday

best regards,
chris

*edit* calculating with half resolution gives the exactly same problem…

btw using that /3GB switch, couldthat cause the error ?

thank you

Try rendering your scene with a simple grey V-Ray material and see if there is still a problem. Also, you might want to check your memory usage while rendering - the light cache may be getting too large. If this is the case, using Screen mode instead of world mode and adjusting the sample size may help to reduce the memory usage. Also are you using any photometric lights?

Best regards,
Vlado

hi vlado
can you also post reply on the other thread about it ?
is photometric lights with lc cause any problems?
there is also some kind of bug with tiles map and i’ve sent you a scene.
