Hi,

I'm currently testing this build and it seems like "Enforcing loading of VDB files just up to the version currently supported (223)" breaks VDBs exported from Houdini to .vdb files. When I launch the IPR I get the following error message:

Code: Select all

unsupported VDB file format (expected version 223 or earlier, got version 224)
cannot read metadata "file_delayed_load" of unregistered type "__delayedload"
cannot read metadata "file_delayed_load" of unregistered type "__delayedload"
 *** OCTANE API MSG: Unsupported VDB file format (expected version 223 or earlier, got version 224)

The exact same VDB gives the following error message but will at least render in the previous release of Octane (2020.1.0.8):

Code: Select all

unsupported VDB file format (expected version 223 or earlier, got version 224)
cannot read metadata "file_delayed_load" of unregistered type "__delayedload"
cannot read metadata "file_delayed_load" of unregistered type "__delayedload"

As far as I've been able to observe while testing Octane since version 4, Houdini has always exported version 224.

I've attached the VDB here: https://drive.google.com/open?id=17v854LuY2OGlAiAQh-M3PuXlnE2nPTJH

Thanks,

sweeet thank you juanjo!

How can the universal camera node be accessed? I tried to find it everywhere, but can't find it.

Either Octane Network or Octane RenderTarget

Yes, sorry. I've reported this issue to the core devs, and it has been already fixed in Octane 2020.1.3.0. I'll release a new plugin build including this new core as soon as possible.

Thanks,
