Hi,

I'm surprised to find only one Octane ROP can be used in a scene. Is there a work around to submit multiple renders in a row?

Best regards

This is a limitation of the Octane 2.25 plugin. The last build of the Octane 3.0 plugin should work with multiple ROPs without problems.

I see... Do I need an Octane 3.x license for this, or will it work with 2.x ?

Currently you can work with Octane 3 using your available Octane 2.2 license, but yes, at some point you will need to upgrade your license to continue working with Octane 3.

I've updated to Octane 3. I can now have multiple Octane_ROPs in a scene, which is great.

I've been trying to render out two Octane_ROPs frame after frame:

ROP_01 frame 1
ROP_02 frame 1
ROP_01 frame 2
ROP_02 frame 2
...

and so on. I can't get it to work right. The first two frames are created properly. Then rendering goes on, but nothing gets saved to disk or the two frames get overwritten over and over (I'll check if it's the one way or the other).

Is this something that could be fixed in the plugin?

You can render multiple ROPs nodes (linked or using the merge node), but currently you must render them "Node by Node", not "Frame by Frame", at least if you are rendering the scene in "update" mode.

Thank you Juanjo, I figured out that works. Are you planning to support the other method? It's very useful for overnight stereo renders.

The problem is that while rendering in update mode the plugin only loads the scene in the first frame, to later update it along the sequence. This is not possible if several ROPs are running at the same time.

Anyway I'll check it again to see if at least could be possible support this feature reloading the full scene for each frame.

Thanks. It's much needed for stereo work. Most of the things people do in Houdini require full scene updates anyway.
