Found a tweak and it looks ok!

Thnx!

Hi,
simple question -> when ?



Thnx,
Alek

NVidia Driver - 431.70 - stable rendering ( last few days 5000+ frames ) scenes around 5-8mln poly

NVIDIA Driver ( latest ) 436.15 - unstable / crashes randomly ~100-150frames

C4D + Octane + Nvlink working
2018.1.3
R17
2x 2080ti

well ... switched off few things and render keeps going ... gonna render scene in a few layers and comp it after :}
Most likely it's about some materials. It can a problem with emission+displacements.

yup. exactly.

switchet off displacement in one material and it worked - rendering from 6007 ...

Hi,
i've got problem with scene i'm working on - using actual build.

Scene is not so big and 2500 frames rendered without any problem - but after frame 6006 cuda error 719 appear - and i've tryed everything...
rendering with each one card alone, with all together, with/withoutout-of-core limit ...
