hi Octane team,
I made a test scene for octane render, and it worked well in direct lighting mode.
But my graphics cards crashes every time when i switch to path tracing mode.
Please help me solve this problem, thank you.

Hi mate
I've tried your test scene and no crashing here.
Notice that Octane 2.43 cuda 3.2 is not working properly with MultiGPU.
Try dissabling your 1GB card for rendering and use only the 2GB one. Maybe it solves your problem
Cheers

Thank you for your testing. :)

Yeah I've already used one gpu each time for rendering.

And even the 1GB one lived longer than the 2GB one(about 2 sec longer LOL).
I found out that lower the maxdepth value of path tracing helped a little, but still unstable.

I think you just stumbled over the Windows GPU timeout check: See http://www.refractivesoftware.com/forum ... ?f=9&t=824

You have two option to fix the issue:

a) Install version 1.022b (http://www.refractivesoftware.com/forum ... =24&t=2509), which will disable the timeout completely. You don't have to run that version at all, just install it and continue woking with beta 2.43.

b) Install the registry change of this post: http://www.refractivesoftware.com/forum ... 556#p45556, which will set the timeout to 10s, which should be enough for almost every scene.

Cheers,
Marcus

Is there a way to solve this timeout issue on Linux machines? Because I'm also getting crashes with heavy scenes & pathtracing. If the rendering veiwport doesn't refresh in something like 5 seconds, the program crashes.

It's the X server that kills Octane. Unfortunately I don't know enough about Linux to solve this problem. I did some search on the internet, but didn't find a way to specify/increase the timeout.

Sorry,
Marcus

If I had two cards, one for display and one for rendering, this issue wouldn't appear, right?

I think I have read something like this in the NVIDIA CUDA forums. You just have to make sure that the X server is not using the rendering card, i.e. it doesn't know it at all. Haven't tried it though.

I choosed solution B and it worked(it's 0.35fps under pathtracing), no more crashes here. :D
Thank you for your help.
