When you take a look at the "Mesher" object you will recognize several "Vertex Maps" tags representing the fluid's channels: speed, vorticity, age, weights, velocity X|Y|Z
...
- If you want to use "Vorticity" vorticity you have to activate → Fluid > Fluid > Compute Vorticity before the simulation, otherwise the channel will not be available.
- The "Weight" channel is makes only available senses if the simulations contains at least two emitters or fluid containers, and requires a slightly different →workflow.
- The "Speed velocity X|Y|Z" vertex maps cannot be adjusted manually.
