Volume object got scaled in IPR Tweet

Please check the attachment screen image
On the left the Volume in viewport shows correctly, but in IPR it got scaled for no reason, so I'm wondering if there is any suggestion for fixing this?

Thanks

This seems to be a problem related to the Houdini VDB primitives internal transformations that are not fully supported by the plugin if you mix grids with different resolutions or if there are nested transformations. There are a couple of workarounds that you could try:

- Convert the Houdini "VDB" primitives to "Volume" primitives using the Convert SOP. This can solve the problem, and it will make the scene extraction time a lot faster too.

- Export the simulation to OpenVDB files and render them using the "Render OpenVDB file" options available in the Octane OBJ spare parameters. This is the best workflow to render volumes because Octane will load the files at the render time, saving a lot of memory and time in the scene extraction process.

Anyway, can you please share the scene file to take a look at it here?

Thanks,
