Hi everyone,
I am at a bit of a loss and hoping someone from OTOY or an experienced Octane Unreal user can help. I have tried many different avenues at this point and want to make sure I am not fighting a known limitation or missing something fundamental.
I am working in Unreal Engine 5.x using the current Octane Render plugin. My goal is to export a 360 equirectangular panorama at around 9200 by 4600 for use in Yulio. I do have a working 360 setup in Unreal using an OctaneRenderTargetActor and an Octane panoramic camera set to spherical lat long, and the 360 renders correctly in the viewport.
The issue I am running into is that the exported EXR is always locked to the Unreal viewport resolution. No matter what I do, I cannot get Octane to export a higher resolution image. I have set the Film resolution to custom values, resolved into a node or parameter, disabled all region rendering and relative region locks, used Octane Viewport Save Image, rendered from the Octane GUI window, restarted Unreal, reloaded Octane, and verified the EXR size outside of Unreal. In all cases, the resolution snaps back in the UI, and the saved EXR confirms it is still viewport-sized.
I also attempted to move this workflow to Octane Standalone. However, in my Octane plugin, exporting an ORBX scene is not available. The Octane menu shows Export ORBX scene, but the export format is locked to Alembic, which means I cannot transfer cameras, materials, lighting, or the panoramic setup into Standalone.
At this point, I am trying to understand whether high-resolution 360 ° panorama export from Octane for Unreal is currently supported in newer UE5 plugin builds. I am also wondering if the viewport resolution lock is expected behavior, whether there is a known workaround or supported pipeline for this use case, or if the recommended approach is to rebuild the final scene directly in Octane Standalone.
Any guidance or clarification would be greatly appreciated. I have spent a lot of time troubleshooting this and would love to understand the intended or supported workflow from now on.
Thank you very much for your time
Charlene
