Hi,
I recently put a second GPU in my computer and worked pretty fine even in octane, but since 2 days everytime i try to switch to render mode it display this error in the log

Code: Select all

CUDA error (101) on device 0: invalid device ordinal
  -> failed to register D3D11 texture
device 0: shared surface output failed
In the standalone version and in octanebench it doesnt seems to have this issue as the render runs smoothly.
Blender cycles and eevee runs perfectly too.
i tried to run on each of the GPU in the device preference but doesn't change anything.

Thank you for your help guys (sorry for my broken english aha)

Thanks for reporting this problem. We will take an investigation.
Can you please try to disable the "Use Shared Surface for Viewport(recommended)" feature on the octane preferences panel and let me know how it goes? Thanks!

Cheers,
Tom
