pyro= Candle =
This shelf tool sets up a preset pyro effect resembling a candle flame. The pyro system has low burn and gas release rates, so it looks smaller and less dynamic than other pyro presets. The preset uses disturbance to perturb the flame slightly. This preset releases almost no energy and so doesn’t use up much fuel.
One simple way to increase the height of the flame is to remap the Emit Range on the Pyro object’s multi-field visualization to make more of the flame visible.
If the object has velocity attributes, the Fluid Source SOP will convert them into a velocity field in the simulation.
To add velocity attributes to the object, add a Trail SOP and on the Trail node set Result type to "Compute velocity".
Use the disturbance and turbulence controls on the Pyro Solver’s Shape tab to add detail or change motion.
Use the noise and scale settings on the object’s Fluid Source SOP to change the emission.
