How to render Blender Octane via RR

[Martin Hebermehl]

Salve,

how i can render Blender Octane Jobs via RR ? I don´t understand the helpfile... i do not use Octane Standalone, i´m using the free version of Blender Octane 2025.3 - 30.7.

Regards, Martin

Hi

 

You have to take a look into the rrHelp section 3D-Blender, not the Archive/Standalone-Octane.

 

Please see “Custom Add-ons”: https://www.royalrender.de/help/Blender.html

 

In short:
You probably have installed Octane into the folder of your windows/linux user.

Which means it is not available for any other person (including RR).

So you have to copy it into a shared folder in RR which is then loaded by all Blender instances on your farm.

 

And Blender does not auto-load plugins automatically, so you have to tell Blender to load the addon.

I would recommend way “A” in the help file as it is easier)

Hello Holger, thanks for help.

I followed the helpfile "Custom Add-ons". Because Octane For Blender is a stand-alone Blender-Version with built in addon for Octane there are no files or folders for this version in  %AppData%\Blender Foundation\Blender\<Blender Version>\scripts\addons\  

The files for this custom built Blender Version from Otoy are in C:\Program Files\OctaneBlender30.7.0\4.5

Anyway i´ve copied all folders inside this folderstructure from otoy to V:\RR\render_apps\renderer_prefs\blender\win_x64\30.7\4.5   (V: is network folder for RR)

RR finds these folder and copied it like this:   Copy directory from '\\de-mst-s3d01\RoyalRender\RR\render_apps\renderer_prefs\blender\win_x64\30.7' to 'C:\RR_localdata\SysUserPrefs\A\AppData\Roaming\Blender Foundation\Blender\30.7'

For your recomended way "A" in the helpfile, i don´t find the "Load Add-ons" checkbox... where i have to have a look ? In the rrSubmitter ? Don´t see anything...

Tried also way "B" in the helpfile.

But the logfile from RR do not tell me, which plugins are found, it tells me only Error: Engine 'octane' not available for scene 'BTY' (an add-on may need to be installed or enabled).

I tried to change the script (Way "B") inside Blender with the name "octane" or "octanerender" or "octaneBlender (which is the name inside Extension-Window in Blender, but i think this is not the internat plugin-name)...

I think because Octane is built-in within the Blender-Version of Otoy this is not a "third-party" plugin like in official versions of Blender ?

The OctaneServer is installed directly in C:\ (no userfolder etc.pp.)....

Yes, it is a job option.

Afaik it was added in 9..16 or .17.

Sorry, did not know that.

I assumed Octane is a plugin like it is for every other render app like Maya, C4D, Houdini.

In this case “A” "Load Add-ons" checkbox will not work anyway.
I will see if we can find some other way to identify 3rd party as well.
Perhaps with the website link of the plugin.

 

I am downloading the special version right now.

Hi

 

I can reproduce that Octane-Blender does not work on the farm.

Perhaps related to this exception (log order is sometimes wrong in Blender):

 

 

 

Another question arises:
Do you want to use the Octane-Blender for everything now?
Or do you need both Blender types for different projects?
Which means RR will handle Octane-Blender as a different render app than Blender.

Like it would handle Nuke/Houdini.

Hi, thanks for help.

No, i do not want to use Octane Blender for everything.

But because Redshift3D for Blender is no longer in development i´m searching for an alternative to Redshift (and Cycles of course).

As an old Softimage XSI veteran i liked Redshift3D so much, also within Blender,  but Octane i think is now the next alternative Render-Engine. And Octane is much more integrated to Blender than Redshift3D...

So it would be nice to render Blender-Octane via RR...

Hi

 

I have a fix for OctaneBlender:
Please see 1) on this page: https://render.otoy.com/forum/viewtopic.php?t=85117

 

And the next RR version has a new render app OctaneBlender.

(Release is scheduled for next week)
