OTOY Forums

Hi,
since one week, out of the blue i'm having octane live viewer giving me errors after few minutes it's loaded.
I looked for some answers on the forum, and as i read i tried to update the bios, fresh installed and downgraded my card driver, tried to use an old octane version, but i still get the error after few minutes
now i'm running on c4d r19.053 and octane 3.07-r2, nvidia driver 398.36 (i have 2 x 1080ti)
i really don't know what to do, any help?
thanks in advance

Here I see that you have a low free VRAM. Do you open/work another software as AE, PS, Chrome, etc at same time of render session?

yes, just chrome actually, i close everything else

Watch your free VRAM while rendering. Sometimes it makes peek for transfering buffers or so. It shows a VRAM error in log.
And it's clear that you have very high export time. It's 180782.363 ms = 180.78 seconds. It's very high. Your material export time is much exposive. 178.5 seconds. What do you have so much?

I always have very dense geometry, since i only render images i guessed having a lot of triangles would not be a problem,
how should i optimise the scene to have a shorter export time and less triangles?
cheers

Also using 8k textures (which i am using) may get in the way for a long export, right?

I may be a problem too. in V3 geometries should fit to VRAM. Be aware of triangle count differences on LV against PV. Check how many triangles in LiveViewer and PictureViewer. Do this by deleting all materials if you cant render in case.

I suppose you're using some C4D shaders like Layer/Noise/etc... right?

not at all, i'm using exported substance painter textures branched in the basic octane channels, i never use layers or even c4d noises on octane materials..

what do you mean with:

thanks!!

I have a similar problem:
The difference is I'm not loading a single mesh or material in the scene... Any thoughts...?
It started yestarday, since them I cant render anything... standalone or plugin...
Already tried to reinstal drivers ...

EDIT:
After making lots of hardware tests I found out its a GPU hardware issue... so one of my 1080s is faulty and doenst render anymore so I had to disconnect it.
Rendering just fine now.
