PROBLEM: Octane render works with Directlighting, but crashes when i switch to Pathtracing.
Checklist:
1. Wrong driver version installed.
Make sure you are running the exact same driver we recommend in the accompanying readme.txt, which comes in the release.
If you are using different drivers, we cannot guarantee stability, nor provide support.
2. for beta1 and lower, If you have a Geforce 8000 Series, or a low-end 9000 series like a 9400, use the octane8000.exe
If you have a Quadro Series card, check on what technology it's based. It can be based on a 8000 chipset too. (use google)
beta2 and up don't have this split system anymore, just one the single octane executable for both cards.
3. If you enable path tracing and you render to a high resolution, a render pass can take long,
sometimes up to a few seconds, because path tracing is more complicated to compute than directlighting.
This is the time the operating system cannot use the GPU, and some operating systems will automatically close the application that takes the GPU for longer than a few seconds.\
This depends on the operating system type AND version.
There are ways to increase this timeout, but we do not recommend them as they involve modifying the registry settings.
If you still want to try, you do so at your own risk.
Turning off 'filter' in the path tracing options (which is enabled by default, and does'nt do anything with the octane8000),
can help as it speeds up the rendering pass.
If you still can't get it to work, you either buy a 2nd GPU, as a 2nd GPU can render passes without being interrupted by the OS,
or you wait until we have released beta3, which will solve this issue.
People on slow GPUs will often have this problem, with pathtracing on high resolutions.
Yours,
