I think this is using VDB (sparse), take a look at that: http://www.orbolt.com/asset/953u6015t::pyrojunior
You cannot do it in DOPs though afaik.

fuosNo idea about that, but I meant sparse as in terms of VDBs. Compression might be possible though? Dont knowSkybar

Oh I was under the impression that losseless compression happens on contiguous areas. Poor looking lossy compression can happen with the Tolerance value on Scalar/VectorFields. VDB should just also have very fast access to voxels as well as being sparse.

Yeah - I can't really find a good definition to differentiate Sparse and RLE style compression and it looks like the Scalar/Vector Field Dops convert VDBs to normal Houdini fields.
Anyways, I guess the next question is what is the difference between an ad hoc field, like Gas Field Match makes, and a proper field that SOP Scalar Field makes. Is it that we can't extract an ad hoc filed back to sops?
