hi guy's
looking for some help with an animation i am trying to render.............
the attached image shows 3 frames, frames 26 and 28 are rendered on a different machine to 27. both scenes are using exactly the same settings/scene/Gi file etc................
as you can see, the aa seems to be degrading in quality on one of the machines!! any ideas??
thanks

Strange. Does it only happen when you render on different machines? What if you render all on one machine? Any problems then?

i am rendering it over 2 pcs..........with frame stepping. its going fine on one of the pcs but the other one is rendering with the artifacts shown above. its almost like its applying motion blur?

Can you try rendering on the problematic PC only and see if it renders allright?

just rendered a frame on the problem machine and it has the same artifact. rebooted the machine and loaded a fresh scene................
its strange that the other machine is still rendering without any problems??

I remember having a similar problem with screamer net a while ago, it turned out that it related to the different processor types, I had a mixture of Apple PPC G4 & G5 machines which gave differing/error renders.
I think I heard about a similar problem when running a mixture of Intel and AMD chips but can't be sure?

thanks for the reply. in this case the computers are all the exact same.
maybe it has something to do with the shared GI file? but then i guess
the error would show up on all the machines and not just one?..........its very strange?

Ok these may be stupid questions but are all the machines using the same OS(with same updates) , version of LW & Kray and type of RAM?
Are all the machines reading the scene files and GI data from a shared drive or are they reading from a local content directory on each machine?

i have checked the lightwave and kray versions and they are the same.
not sure about the ram though? the os is the same but regarding updates thats something i should look into.
the scene files and gi file are on the local drive on each of the machines, so there is no connection between them, they are rendering every nth frame.............

Try mapping all the machines to a single drive so each machine is reading exactly the same data
