Render failure // OCTANE RENDER

Recommended Posts

TheOtherOne    5

 Hello boiiiiis and gurls

 

 I just started working with Octane Renderer. I downloaded a demo version. 
  But sadly every attempt ends with prompt of Render failure. Check Octane Render log window

 and there i found:

<<< Render failure detected!!! >>>
Please check render statistics to solve the problem.
Triangles:0  Disp.triangles:0  Hairs:0  Meshes:0
Device:0 TotMem:2Gb rtData:341Mb film:4Mb geo:0Kb node:2Kb tex:0Kb unavailable:1.645Gb
VRAM used/free/max:345Mb/17Mb/2Gb
Free VRAM is too low!
Try to decrease polygon counts and use out-of-core for textures.
Use 'render instances' when it's possible.' 
 

 

 What should I do?

 

 I'm working on late 2012 iMac
3,4 GHz Intel Core i7

24 GB 1600 MHz DDR3

NVIDIA GeForce GTX 680MX 2048 MB

Cinema 4D student version R 18

 

 Whole Renderer doesn't look stable and crashes a lot.

 I downloaded the newest CUDA drivers.

 

 Thanks for helping me out :)

From my experience, Octane is pretty much useless with anything less than 6GB of video RAM. 

 

Your GTX680's 2GB is simply not enough to run octane, hence these errors. 

 

The only solution is to get a better GPU (or another rendering solution).  

 

There are some discussions / comparisons between octane and other rendering options in the Redshift for C4D club, and a lot more info in the rendering subforum.

I have used a lot of Forester stuff, etc with 2 (I only have 4 now) but in your case, something is hogging your VRAM besides the 345 mbs in your scene.

  • nerv and Anthony, Thank you guys for a great response. I also send feedback to the Otoy team recently.

     They also suggested optimising the scene by lowering the geometry.

    Hah It would be it, but not in my case regarding my scene contains only a simple cube and a source of light.

     So it must be insufficient VRAM memory.

     To be honest this is the first time I'm approaching this problem. I need to educate myself on that matter.

    Since I'm very interested in rendering in Octane I'm thinking about changing to the PC.

    It's been a 2,5 years form me in working with C4D so I think it's time for something new :)

    I need to do some hard research, any suggestions guys where to start?

    I know how you feel. After about 10 years using strictly Macs, I found myself switching over to Windows.  A powerful PC will always be cheaper / easier to customize than a mediocre Mac. Sad but true.  The transition was a little rough at first, but after about a year - it just feels normal now. 

     

    There's lots of hardware knowledge here and on multiple other related forums, so searching will be your first best bet. You can just post any unanswered questions after. 

     

    Good luck!

    Haha the pain is pretty big :)
     As a little kid, I used to use windows (98 !) PC. I was using PCs until I went to college and decided to check the OSX and I bought an iMac. And I loved it. Working in Photoshop, 3D programs etc. is flawless, but when it comes to the hard renderings it's no longer that nice.

    But on the other hand, I and my friend were doing some project, me on my mac and he on his powerful PC. During one evening he experienced two bluescreens while mac was working 10/10.

     I also spoke with the Otoy team member and he also said that the error is caused by the insufficient GPU memory and they noticed the NVIDIA GeForce GTX 680MX support only 2gb of VRAM while recommended are 4gb :(

     

    So yeah I think selling mac and buying pc is coming.

     

     

    Thank you guys so much for the responses. I'm doing research rn and I gonna post the conclusions here so I'm not closing the topic.

     

     C U !

    Hello folks! 

     

    I'm having similar issues, bought an EVGA GTX 680 for my MAC Pro 2010 (Intel 2x3.46GHz, 64GB DDR3, originally ATI 5770) to be able to render in octane, after effects and premiere, I setup a very simple scene (cube, sphere, cylinder and 3 lights) and everytime I hit render the MAC just reboots straight away, I don't even get a error log or something.

     

    I'm wondering if the GPU is faulty, but to be honest, using the computer normally doesn’t seems to have any problems, browsing internet, any office applications and even some graphic design APP’s such as Indesign or Photoshop, including some gaming (Counter Strike GO, Diablo 3, World of Warcraft) all worked completely fine, the problem comes using the GPU for rendering with Premiere PRO, After Effects, or Cinema 4D using Octane.

     

    All the times I tried any of these with the GTX680 the computer just turned off after a few seconds of render. I also have a PC with EVGA GTX 1080Ti which I tested on the MAC Pro, I had to install the NVIDIA web graphics to get the 1080 running on High-Sierra and tried the same APPs, all worked fine. I did also some tests with the GTX680 and web graphics but the same problem occurs.  I did check about the compatibility between the GTX 680 and seems that all app's including octane are fully compatible.

     

    Except from octane which needs CUDA, I tested the same after effects and premiere renders with the ATI 5770 and all also worked fine, that's where my questions come, is the EVGA GTX680 not strong enough to run octane? if so, why would be recommended on the octane and NVIDIA website?

     

    or this may be a faulty GPU as the same crash/re-boot happens when intensely using the GPU?

     

    Sorry if this is not the correct place to pos but as I saw a similar problem with similar GPU...

     

    Thanks in advance,

     

    lucas

    That particular GTX680 must have a flaw because I used to have a GTX580 that worked fine so the number of cores, etc should be adequate.

    Thanks for your reply mate. I thought the same, before I bought it i did some google search and found quite a lot of people using it and apparently no issues.

    Still doing some tests to make sure but no luck for now. same issue happening all the time.
