Yes. I already deleted 801 config file.
but nothing changes.

My all Plug in is....

Next thing to try is to reboot and try rendering again. If that does not fix the issue - then it looks like one of your plugins is effecting the Octane plugin. Do you have all those plugins also in 701? Does disabling all plugins other than the Octane plugin fix the problem?

Another question - have you installed the Octane plugin ONCE and are running that one installation on both Modo 701 and 801? Or has the plugin been installed into a different location for each of the two Modo versions?

Once you find out the plugin causing the issue - pls let me know and I will see if I can contact the plugin developer.

You have done it correctly - the same plugin should be used for both 701 and 801.

Hi paul.
Thank you!!
I'm checking one by one.

Hi paul.
I Found it!!
Vray beta program!!
Vray Beta program had caused the problem.
I uninstalled Vray.
zmq error message and octane error message is gone.
now, I did Reinstalled Vray Beta program.

This error means that Octane can't initialize the CUDA API. Unfortunately we don't know why that happens. The CUDA API is provided by the CUDA library that comes with the graphics driver. Since a few people have reported this problem recently, and we never saw it before, my best guess would be that the driver you are using has some issue when different functions of the same process (but different modules) try to initialize the CUDA API.

-> Maybe try a different driver.

I have refreshed the installer at the top of this thread with:

2.12.1.37
- Compiled with Octane 2.12
- Now both the currently viewed render pass and the current rendering render pass are displayed in the Render Statistics window
- "Reload Mesh Each Frame When Animating" property no longer need "Live Geometry Update" ticked in order to be accessed

Sweet, thanks Alot! Now the PMC is back up to speed again, just wonderful news!

Paul I have a scene with several instanced mesh lights and I noticed that the Live geometry options dont work (camera visibility, shadow visibility)

1. Start a new scene and add a unit cube
2. Instance the cube move them side by side we see both
3. Open octane viewport
4. Select original cube and enable live geometry updates
5. Reload the viewport
6. Disable camera visibility on original cube

RESULT: nothing happens. Both cubes are still visible

Another problem is that we dont have any "octane mesh" options on instances. There is no way for me just to disable "camera visibility" on the instance only.

You are right Funk - I hadn't noticed that before. A non-instanced Modo Mesh which is "live" will be connected to an Object Layer Map node - which has the Octane visibility settings. However a mesh which is also an instance source will be connected to a Scatter node (and the source and all instances are transforms in the Scatter), so there is no Object Layer Map node for the visibility.

One solution would be for the plugin to add an Object Layer Map node to the output of the Scatter - then turning off the visibility of the Mesh node would turn off it's visibility, plus all instances. Would that work for you? It will not be possible to have Visibility on Mesh Instances because the Scatter node does not support that, however you can just turn off the Modo visibility for the Mesh and that instances transform should be removed from the Scatter.
