hello
I have octane 2020.1.5 with C4d R20 and I have an old scene builded with Octane V4 now I have this log error:
OctaneRender Studio 2020.1.5 (8010500)
Too many nodes
CUDA error 719 on device 0: unspecified launch failure
-> failed to copy 2D array to device
CUDA error 719 on device 1: unspecified launch failure
-> failed to wait for event
device 1: direct light kernel failed
Too many nodes
How I could fix that
thanks

Hi Giuseppe,
do you have NvLink active, but Out-of-core is disabled?
If yes, please enable also Out-of-core, it is necessary for moving textures to system RAM, while geometry is handled in NvLink/VRAM.

hello Beppe
thanks for the reply
I don't have nvlinked gpu's and it don't appear into nvidia control panel.
Regarding the out of core subject, in the settings I have enabled it but with default values (4gb for RAM usage limit, 512 GPU headroom), I have 64gb RAM, maybe I could set more higher values?
thanks a lot

Hi Giuseppe,
no, default settings should be ok for Out-of-core.
Please, download and run GPU-Z:

And share a screenshot from the Graphics Card tab, for all the available Nvidia GPUs, thanks:
Which exact version of Win 10 are you using?

Hi,
you are using DCH version of Nvidia driver, but before switching to Standard version, do you mind to share with me a scene that is giving you CUDA error 719?
Please, save the project with assets, compress the resulting folder, and share it with me via Private Message.
You can also share a link to dropbox or google drive, or any other similar service, thanks.
