VDB instancing - Artefacts

[jtmsf]

Hi

I was experimenting with tiling a .VDB volume to see if it was possible to make a cloudscape using VDBs inside Octane for MODO.

Imported a single .orbx proxy to a mesh, replicated it using a particle generator, changed scattering and resolution inside the "edit proxy", and made a test rendering

Really bad artefacts in the intersection of the VDB replicas

Tried different volume resolutions. Same thing.

Is there any workaround or it's a limitation?

Thanks for any help

Hi - may I suggest exporting the scene to Octane Standalone, and if the problem happens there too, submit the scene to OTOY in the Octane Standalone thread where they can investigate.

Thank you for your help

Just a quick update. I made more tests with different resolutions and settings. This was the result

Before VDB intersection

After VDB Intersection

Exported to Standalone, same issue.

Will submit a request to Standalone team as suggested.

Thanks
