hi all!
I made a thread about this problem before The Great Forum Disaster, but since I've been on holidays - belileve it or not - without internet access, I wasn't able to see if there were any answers. And now since the old thread is gone, I decided to repost it.
So - here it is again.
I've been having issues with how reflections/shading is calculated with DR enabled.
Scene is pretty simple - one object, no GI, HDRi in reflection slot, a few vraylights, physcam, nothing fancy. When rendering locally everything is OK. But if using DR there are strage atifacts, buckets from slaves are generally brighter and the reflections'/shading look different.
here are some examples:
shading/reflections?
very visible/very annoying/ DR buckets are bighter
more subtle, but still...
...and since it's an animation, the flickering is so horrible it ruins the whole thing. Of course
I can render it locally, but it will take ages - originally it's in HD, about 2000 frames, some over 20 minutes to render. With DR they take less than 4 minutes, but You can see what happens...
I checked the HDRi - it's identical on all slaves (maps are stored locally on all slaves),
here's what I did to try to avoid the problem:
disabled mblur - nothing
disabled hdri reflection - nothing
tweked the settings a bit (noise thresh and such) - nothing, but it seems to be slightly less visible with noise threshold below 0.01
checked the geometry for any overlapping faces - all is OK
disabled 2-sided material - nothing
If anyone has any idea what's wrong - please, let me know. I'm on a tight schedule with this job, and really need help...
the setup:
xp/32b
max9/32b
vray 1.5 sp2
one workstation and two dual slaves.
cheers!
