Using FLIP DOP Controller
Set DOP Network, press Connect Parameters, then work from this panel. Connect writes channel references onto the targets, so the values live here and the sim reads them.
What goes where
FLIP nodes are found by type, not name; more than one of either and you are asked which. Voxel Size connects to nothing — no FLIP node takes one.
The Link checkboxes
They decide whether Connect includes that parameter. They do not switch the parameter off. All default on.
Unlink
Removes what this node wrote and freezes each target at its current value. It only removes its own expressions; anything else is reported and left alone. On Connect, a foreign expression is taken over, and named in the report.
Add Linked SOPs
One row per parameter driven: the SOP, which value to Send, the Target Parameter, and a Multiplier. The target is typed explicitly because the name is not stable — Particle Fluid Surface 3.0 uses particlesep, version 1 uses stepsize. One that does not exist is reported, never silently skipped.
Leave DOP Network empty and Connect drives only these rows.
The container box
Drives the solver's Volume Limits. Match Input Size fits it to the input; Match Size to Parms bakes that into Size and Center and switches the fit off.
There is no Rotate — the solver's Volume Limits are axis-aligned, so a rotated box would draw one boundary while the sim enforced another.
Traps
- Particle Separation is the one that matters — halving it is roughly eight times the particles.
- Time Scale slows the whole DOP Network, every object in it, not just the fluid.
- Status is a record, not a live watch. It does not see hand edits in the dopnet.
