I did some water bubbles and found, that using the fireball preset gives some really cool results. To get a mesh from the fireball, I used Convert Volume and played with VDB until I got a cool hero water bubble.
One thing that makes me wonder is, that when I try to render it with redshift, the meshed fireball will still be rendered as a Volume. When I cache the bubble as alembic, I have no more velocity. The velocity is missing as soon as I use convert volume.
Instead of using “Convert Volume” I am using now “scatter” to get points on the PyroFX and mesh it with the VDB workflow. I than used a “popnet” and “pop advect by volumes”. Finaly I made a “Attribute transfer” from the popnet to the final mesh and got my velocity.
In Redshift I have to tick the Object Parameter under the tab “Render” the “Deformation blur from velocity”
