Hi,
I can't save out simultaneous alembic &vdb sequence.
Alembic is saving out, vdb not.

What do I have to change in the ROP?

There is no ‘simultaneous’ anything in houdini. Operations are performed sequentially. (It's possible using PDG, but that is not what is used here.)

In place of the file sop. Use a geometry rop. Then you could fetch it the same way you have the alembic rops. This way you can set up a dependency.

A word of advice, NEVER use a file node set to write or automatic.

I also stress to never upload a file with a live file node set to write.

Thank you for clarify.
I didn‘t mean that all severs shoult write at rhe samw time, I mean

Saver A Frame 01
Saver B Frame 01
Saver C Frane 01

Saver A Frane 02
Saver B Frane 02
Saver C Frane 02

Just that I can write out the files at the same time.

Sorry for the active file saver node.

I have just problems, that the VDB isn‘t saved out.


Thank‘s

The problem in your scene was the missing node for writing the vdb.

The fetch node is not pointing to anything in your scene.

Add a rop geometry sop in place of the file node, and update the fetch's path with that of the rop geometry node.

Thanks a lot for the example file, I have to check again, because even if I change the
fetch path to where the vdb is coming, it won't write the file at moment.
But maybe I have something other who is missing.
