OctaneRender® beta 2.43 (lin/mac/win) [OBSOLETE]

[matej]

hm, I ran into a major problem here.

Earlier this morning I played with the cuda 3.2 version on Ubuntu 10.10 and everything worked right. Then the system needed to do some major updates (it's freshly installed) and after I rebooted I went to my other OS (Ubuntu 9.10 with cuda 3.0) to check if Octane 2.4 for cuda 3.0 works right (which it does). After I booted again in Ubuntu 10.10, Octane for cuda 3.2 stopped working.

It loads the scene and all, but it just wont start to render - anything, not even the preview ball. It doesn't load stuff in to the VRAM and start the rendering process no matter what I tweak or add to the scene. If I do something that would normally trigger render re-start and then try to load another scene or a new scene, it crashes. There are no useful hints in the console output (illegal instruction). Octane correctly recognizes my graphic card.

The system update didn't change my video drivers (260.19.29) which worked fine earlier, but maybe did some changes to the CUDA toolkit? I'm not sure, the list of updates was huge (200mb) and I didn't bother to read it all. Should I try and reinstall drivers & cuda?

quote matej:"..I'm not sure, the list of updates was huge (200mb) and I didn't bother to read it all.."

since a few weeks ubuntu asks me to update so many items.. but unitl the end of comp i will wait.
i often encountered similar problems after updating a lot of stuff (which i really didnt knew) with this automatic "updates function".
suddenly a lot of applications did not work anymore...

i would try to update again the 3.2 cudatoolkit.

good luck

Yep, that should work.

Yep, I would reload the driver. You might want to make sure that there isn't any CUDA 3.0 left lurking somewhere. I had a similar situation on Fedora 12, I had an update and Octane stopped working. I took it a bit farther and decided to upgrade to Fedora 13 at the same time. I ended up in an almost catch 22, no working video driver and a non-working nouveau. Luckily the Nvidia driver installer has a -z option that forces it not to check for nouveau. So in the end I was able to install the Nvidia driver and then blacklist nouveau. After that Fedora 13 came up with no problems.

Thank you guys. I'll try & reinstall the drivers later in the afternoon. I'm working on Ubuntu 9.10 with 2.4_cuda3.0 right now. Good timing

btw, mine was a fresh install of Ubuntu 10.10 with cuda 3.2, there were no previous cuda or driver installs on this system.

more btw, the material pin highlight feature is great

Hmm, maybe it helps to completely delete the directory /ust/local/cuda and then reinstall (in that order)
- the latest NVIDIA driver (http://www.nvidia.com/object/quadro-mac ... river.html)
- the CUDA 3.2 toolkit (http://developer.nvidia.com/object/cuda ... html#MacOS)
- the CUDA 3.2 driver (http://www.nvidia.com/object/macosx-cud ... river.html)
?

Or just wait for the CUDA 3.0 releases, which I'm currently preparing and which will be available in 2-3 hours.

unfortunately it's exactly what i've done.
i've spend all the morning uninstalling and reinstalling but nada
the bad news is that i've the same issue of matej and i can't go back to cuda 3.0 with osx 10.6.6. the problem for me is in the new drivers for the GTX 285 mac, i can't find a way to deinstall it.
i've installed the 243 cuda 3.0 on the PC and i like it very much but my workflow is broken. i'm very sad, this is the first time that i can't run octane on my macpro

I would like to see an alpha channel to work in direct light.

How to go back to cuda 3.0 on Vista x64?

[tungerz]

Question for the Tech Godz...
At the moment I am running 32 bit vista, w/ geforce vso 9600 (I need to upgrade to a new 4xx or 5xx card badly)... if I upgrade to 64bit windows 7, how much of a gains will I see in regards to Octane? Load higher res meshes?

Thanks in advance for all of your time and knowledge.

Cheers,
Happy Rendering...

Just use the CUDA 3.0 build. You don't have to do anything on the Windows side.
