OTOY Forums

Hi,

This can be done in Octane Blender using some workarounds.

Please check the attached sample. To utilize the scatter attribute, we need to use the instance color/range nodes because the float/color vertex attribute nodes do not work in these cases. Additionally, Octane supports only one type of scatter attribute - the scatter ID.

Here's the workflow:

Use "GeoNode Attribute" for the source as Scatter IDs.
Set the attribute name according to what it's called in the GeoNodes.
Use Octane's instance nodes as workarounds to achieve the desired output.

Please note that this applies only to the custom-built version, as the Addon's Python APIs do not support fetching the GeoNode attributes.

I'll see what I can cook up with this method, cheers Lino!

Sure!

Hey Lino,

Just checking in any updates on adding support for Geometry Nodes’ “Instance Domain” attributes in Octane? This feature is crucial for my workflow, and its absence has been a significant limitation. Could you please provide any information on the current status or expected timeline for this implementation?

Thanks!

We need changes to the Octane engine to be able to support what you're asking for, so defining a timeline for the implementation is not possible for me at the moment. I can ask if that's something planned for future versions.

Is there any way to use more than one color instance attribute? The method shared above works well but only supports a single object instance attribute

should we expect the new version like octane 2025 or 2026 may support this issue?

I can only second that It would be really great to have that asap

We're doing our best to support this kind of setup in Geonodes, but that's not trivial at all.
