Hello,
I'm trying to deform a pyro volume with a Lattice from Volume SOP.
However, it's throwing the following error:


At first I thought it might be data in the source pyro VDBs, I deleted everything except density.
I'm still getting the above error.

Please find attached a simple test hip file that loads this pyro volume:

What am I missing?
Thanks

your pyro cache contains houdini volume primitives, not VDBs
to convert to VDB you can use Convert VDB or Pyro Post Process SOP, ideally before caching, or check convert to VDB on Pyro Solver SOP/Output tab

I'll give that a try.

Thanks

That worked! Many thanks, Tomas! 🙏🏽
