- If the emitter Id is 3, for example, "Min Value" has to be 2.9 and "Max Value" is 3.1
- An emitter's Id is shown in the HUD.
"Vorticity" has to be activated in the → fluid container (all fluid types, except "Dumb" have a "Compute Vorticity" option) before the simulation starts, otherwise the condition will never be fulfilled and there won't be any filtered particles.
Value
This is the trigger value for the condition. Please note that this field is inactive with “Condition” set to “In Range”, “Out of Range” and “Expression”.
...
This field becomes active when “Condition” is set to “Expression”. RealFlow constantly checks against the given expression during a simulation and decides whether the condition is fulfilled or not. There is a long → list of keywords that can be used to create a certain condition.
Split
When the given condition is fulfilled RealFlow will create additional particles – their number is defined under “# child”.
# child
Here the number of child particles is specified when a certain condition is fulfilled. You should start with moderate values, because the amount of additional particles can become huge.
Bounded
With this option it is possible to restrict the daemon to a certain volume.
