Apologies for a cross posting but... - I'd like you to consider this - it seems VfR has a memory issue in large scale batch rendering with big models,..
Guys - we have been trying to do an animation of an aircraft interior here - around 4 mill. faces - a full business class model - I really don't want to share the model as it very confidential and includes data from other suppliers we are contracted not to release.
It would get to about 9-10 frames and then report an error and crash. (It said something like 'encountered a problem/ exception' - it is taking Rhino down with it and then creating the RCM dump file - sometimes blaming Brazil.
I deleted half the model to have only two seats - (moving in Bongo) this got to about 50 frames and then same result.
It will render out the wireframe ghosted no problem.
I tried Bongo and the straight animation path in Rhino - with same results.
Bongo has its faults - but the problem I think is VRays use of memory in batch rendering mode.
My own gut feeling is that some memory is not getting released between frames and it eats it up until the whole thing hangs. Having a shed load of RAM might be a temporary work around - hey - maybe write to disk - just for now?
This would explain the ability to render lots of frames with simple models - but not with bigger models and there is a sliding scale- this is currently a big show stopper as we have left MAX to use VfR and cannot afford the time to translate our models back.
The machine is Dell M90 Core Duo around 2GHz with 2 GB RAM and a good NVidia card.
I might try and do a single QTVR as a workaround. Finally for those supporting VfR - which I do wholeheartedly by the way - try something like Sony Vegas or Final CUT Pro at the Video edit stage - one can do wonders with panning and cropping single scenes to mimic 3D - I know we had to.
BTW this was never an issue with 3DSMax - although we had various distributed rendering SNAFUs instead.
Good luck fixing this guys....
