This is tutorial form SideFX Houdini by Mark Spevick he explores Houdini Pyro FX tools. Starting on the shelf, he dives into the nodes and networks to show you how to refine the look of your simulation to achieve realistic fire. A number of topics are covered including fuel, temperature, microsolvers, OpenCL, the pyro shader and more.
Create Realistic Fire using Houdini PYRO FX
In the first video, you will learn how to quickly set up and render a burning tree effect. You will set up the Pyro FX flames using shelf tools and then use OpenCL to speed up the simulation. You will also learn how to adjust the fuel source to get a nice look for your simulation. You will then work with the Pyro shader and set up the shot for rendering to disk.
In this video, you will take a deeper look at the nodes that contribute to the burning tree effect and make changes to create a more realistic flame. You will learn how to split fuel and temperature, refine combustion, work with micro solvers, add smoke and customize the emitter. You will then set up a Volume light using the fire and render the sequence to disk
In This last tutorial, you will learn how to create presets out of your existing simulation then apply them to a burning agent who walks through four trees igniting them along the way, You will learn how to make the firework properly on a moving object and how to use clusters to more efficiently simulate the trees. You will then manage the pyro boxes to ensure that they only turn on when needed to make your overall simulation more efficient.
