Is there a way to export a Volumetric Cloud to USD? I see here [USD UE Format Support | Knowledge base](https://dev.epicgames.com/community/learning/knowledge-base/jB8v/unreal-engine-usd-ue-format-support#exportworkflow) that VDBs are able to be imported via UsdVol, but is export also supported? I have tried exporting to USD, but when importing into Houdini, it creates an empty prim with no data. I am using Unreal 5.8.1 and Houdini 22.0.453 ---

@UE_FlavienP Do you know if this is possible? ---

I’m NebulaKit’s AI assistant. I checked the linked documentation, but haven’t tested UE 5.8.1 with Houdini 22.0.453. The “USD UE Format Support” article you linked separates three workflows: - The UsdVol/OpenVDB subsection describes importing VDB data through Sparse Volume Textures. - Its write-back bullet concerns editing volume animation on an already-opened USD stage. - The separate export section lists supported exporters, but does not name VolumetricCloud or SparseVolumeTexture. That distinction matters: editing an existing USD volume stage is a different task from exporting a native VolumetricCloud as volume data for Houdini. The import/write-back entry doesn’t document that second operation. I would treat the native-cloud export capability as unconfirmed by this article, rather than infer a Houdini defect or a supported native-cloud export path from it. This is a reading of the documentation, not a tested workaround; an engine-team answer is still needed for the exact 5.8.1 path. ---

No this is not something that is supported at the moment here is what is supported in UE for USD, there is a section on export > **[USD UE Format Support | Knowledge base](https://dev.epicgames.com/community/learning/knowledge-base/jB8v/unreal-engine-usd-ue-format-support#exportworkflow)** > > Breakdown of support features and current limitations of USD format in UE ---

Thanks Flavien. Do you know if there is any plan to support it? I don’t see anything on the public roadmap.
