OctaneRender™ Standalone 3.05.3

Well this is a solution but not very practical, I indeed already mentioned my wish for a light material list which would be very useful too but this is something else, though light materials list could help. What I think would be very useful is a set of materials linked to the RT which would be applied to the meshes linked to this RT, I mentioned lights materials because it is probably the main need but it could be applied to any material, so this way you don't have to care about linking/unlinking materials to the mesh when switching between RT.

Hi Enrico,
maybe I'm wrong, but what you are asking, is not what we already have with the material map node?

Oh s..t, exactly what I need. Didn't know that several material map nodes could be linked to the same mesh. Still alot to lean
Thanks Beppe.

(from jan 11 -> In the next 1-2 weeks we plan to release a test build of 3.06 ) When 3.06 will arrive?

Tks

After several hours of trying I realized that the problem is more complicated
for commercial models with textures.

It seems that "Ni" in the mtl file confuses Octane. If I remove all "Ni" lines it will load all textures.

THANK YOU SO MUCH!!!
Seems that this solution worked just fine.
I have no idea what the Ni parameter is about but the textures are loaded just fine.

Thank you so much Zay for your support.
It would have been really interesting if someone from the fantastic Otoy team will be able to fix it (I do not know if this is difficult or not.....hope it is something simple) so it will not be necessary to edit each mtl file seperately and make the octane workflow smoother.

Thank you again.

Alwyn (aka haze) is looking into it.

Hi there!

I have issues with the standalone version on Linux (Mint 18.1) - it wont render. I have recently installed a GTX 1070 and fresh Linux install with 375.26 proprietary Nvidia drivers. When I try to render with Octane 3.05 & 3.04 it hangs, repeating this error over and over:

Code: Select all

CUDA error 712 on device 0: part or all of the requested memory range is already mapped
  -> failed to pin memory
device 0: failed to pin film buffer
device 0: detected an error on render device! trying to recover...

The drivers installation went smooth, the Nvidia settings recognize my GTX 1070 (and the 550 I use for display) and so does Octane:

Tho, if I run lspci, GTX 1070 is not properly named. Not sure if this is an issue or not:

Code: Select all

01:00.0 VGA compatible controller: NVIDIA Corporation GF116 [GeForce GTX 550 Ti] (rev a1)
02:00.0 VGA compatible controller: NVIDIA Corporation Device 1b81 (rev a1)

Note two additional things:

1.) I'm able to render with Cycles (Blender 2.78) on the GTX 1070 in the same Linux environment just fine
2.) Octane 3 works on Windows 7 on the same machine. (tried the demo version 3.04 just to test it)
EDIT:
3.) Octane 2.26 works just fine

The error message is most likely because mapping of the film buffer into device memory fails for some reason. Maybe try a different driver.

Does it happen on any scene or only on a specific one? If it happens with any scene, maybe try enabling the 550 and then disable the option "Use for tonemapping" for the 1070 and let me know what happens.

There will also be a test build of 3.06 tomorrow, maybe try with this one, too.

Hi, I did that (tested on Octane bundled test scenes) and the 1070 still fails (but at least it doesn't hang in this case):

Code: Select all

CUDA error 101 on device 0: invalid device ordinal
  -> failed to bind device to current thread
device 0: failed to initialize resources
device 0: failed to recover - giving up and switching device to failed

Will wait for 3.06 and then try to install different drivers if it still wont work (but I've already installed the latest stable ones for Linux, like 10 days ago, so maybe I should try to downgrade)

Anyway, let me just note again that 2.26 works just fine in the same system & machine. And 3.0 also works on the same machine, but on Windows.

Matej, it looks like you and I are running into the same problem. See my thread regarding my problem.

Is there a chance we could get the module SDK in the standalone downloads for 3.06? I just downloaded over a dozen versions only to find none of them had the SDK in them, even the version I had previously.

I get nvlddmkm.sys BSOD occasionaly when Octane is in full swing rendering and I start After Effects or Premiere.

If you get still BSoD using Octane Render standalone only then -> Try to use DDU? - viewtopic.php?f=11&t=55444&p=283899&hilit=+ddu#p283899

EDIT: conflict CUDA used (OR and After Effects or Premiere simultaneously) may cause BSoD.
