Render failure error in Live Viewer.

[Gumz]

I need a helping hand. When I make any adjustment to materials while Live Viewer is running, I get this error message:

"Render failure! Please check Octane Render log window from -> Settings -> Other"

When I do that it says:
"CUDA error 700 on device 0: Error code unknown.
-> failed to unload module"


And in the log it also says:
"Failed to free page-locked memory"

It's a driver issue? I have updated it not long ago. The driver version is 347.25

[Gumz]

Never mind. I'm an idiot. Updating driver to 347.52 fixed it.

[Gumz]

No. It isn't fixed. The problem seem to start when I use images in materials.

I'm using 2.21.1 by the way.

I've been pulling my remaining hair out of my head all day, but I think I found the problem.

When I turn of Out Of Core Textures the problem goes away.

Hello
I've encountered "CUDA ERROR 700 on device 0" several times.. + "could not deallocate memory info"
I have turned on "OUT OF CORE" settings, but it crashed Octane & C4D

ANd I also have this : "Tried to access Null item" do you know what it means ?

Thx in advance

it's a little warning message. Means that plugin try to connect unavailable mesh slots, but not critical. That's not a reason for your problems.

Cuda errors, that's not a bug. We can't catch it before sending data to CUDA. It means that somethings are not fitting to gpu's vram or limits. You should hide/delete some objects or materials to find which causes this.

OK thx for info

I have to admit the amount of objects in my scene has gone out of hands !
I'll search for what is power consuming

take care
