This shelf tool is deprecated. Use the Smokeless Flames tool on the SOP Pyro FX tab instead.
Overview ¶
Note
The effect created by this tool in Houdini 12+ and later looks different from the equivalent preset in prior versions of Houdini.
This preset uses a low gas release rate to create persistent flames without an explosion. It has a high heat output so the smoke from the fire rises faster than the flames.
On the Pyro solver node…
-
Use the Smoke amount to control the amount of secondary smoke.
-
Use the Shredding controls to rip the streaks apart.
-
Use the Disturbance and Turbulence controls to add detail or change motion. Flames usually need high turbulence.
-
For more detail you can also lower Temperature Diffusion.
-
Use Flame Height to change the height of the flames.
-
For thicker smoke, turn on Create Dense Smoke and lower the Heat Cutoff.
See how to use the pyro tools.
Tips ¶
-
If the object has a velocity point attribute (
v), the
Volume Rasterize Attributes SOP will
create a velocity volume for the simulation.To add velocity attributes to the object, use the
Point Velocity SOP. -
Use the disturbance and turbulence controls on the Pyro Solver’s Shape tab to add detail or change motion.
-
Use the settings on the object’s
Pyro Source and
Attribute Noise SOPs to change the emission.
