Octane crashes constantly

I'm having tons of issues using Octane with Unity. Anyone else?

I am using Unity 2018.4 and OctaneRender 1.2.0.1370.

I'm trying to use it in realtime with the render view and I can't go 2 minutes without the renderer crashing and throwing this error. Help!

Code: Select all
CUDA error 700 on device 0: an illegal memory access was encountered
  -> could not get memory info
CUDA error 700 on device 0: an illegal memory access was encountered
  -> could not get memory info
CUDA error 700 on device 1: an illegal memory access was encountered
  -> failed to unregister pinned memory
CUDA error 700 on device 1: an illegal memory access was encountered
  -> could not get memory info
CUDA error 700 on device 1: an illegal memory access was encountered
  -> failed to unregister pinned memory
CUDA error 700 on device 1: an illegal memory access was encountered
  -> could not get memory info
CUDA error 700 on device 0: an illegal memory access was encountered
  -> failed to load symbol data to the device(deep_data)
device 0: failed to upload the deep params
CUDA error 700 on device 1: an illegal memory access was encountered
  -> failed to load symbol data to the device(deep_data)
device 1: failed to upload the deep params


EDIT: OK so update, I guess the cause of the crashing is trying to operate in real time? I have set my render target as the "Editor" so when I am making live changes and it tries to render as quickly as I am making live changes, it crashes. Is this not a technically feasible way to operate with the renderer?

Are you using the latest nvidia driver?
Which GPU are you using?

I'm using 2 2080's with latest driver version 430.86. I've mitigated it a great deal by disconnecting the 2080 displays and moving all my windows to a 3rd GPU that isn't being used for rendering. So now there isn't any other process that disrupts the renderer. Now it happens a lot less but will still happen a couple times within a 1 hour session. Usually when I am changing settings or switching the render targets. :(

Does the issue will happen with the latest build? We upgraded to Octane 2018.1.3. It might have fixed your issue.
If it hasnt, you should post your issue on viewforum.php?f=33
