Import the butterfly body in Houdini, clean up attributes, and craft wings using the alpha map trace. Align UVs and center pivot to prepare shading and future wing animation.
Use vellum to simulate butterfly wings, pin the animation with a pin group, adjust bend stiffness for realistic stiffness, and cache the simulation for the next lesson.
Learn to advect particles from volume velocity to create a detailed smoke simulation in Houdini, wiring pyro sources, velocity fields, advection, wind, and turbulence, then cache the simulation.
Prepare a Houdini scene by refining butterfly body and wings, applying color swap, aligning scales and placements, and importing geometry, particles, and smoke into Solaris for final rendering.
Import the scene into Solaris via stage context, bring in body, wings, particles, and smoke, merge them, set up a dome light and material library, and render with caramel render.

Hello and welcome to this magical fx course. We are going to create magical butterfly FX in Houdini.
Some Of The Topics Covered In This Course
Creating Geometry With Alpha Maps
Procedural Animation With CHOPs (Channel Operators)
Soft Body Simulations With Vellum
Forcing Vellum Constraint To Follow Animation
Particles Simulation
Shading Particles With Image Texture
Particles Advection
Smoke Simulation
Working Inside Solaris/LOPs
Working With MaterialX Shaders
Rendering With Karma XPU
Compositing In After Effects
First we will start with creating the butterfly wings and then we are going use the chops to create wings procedural flapping animation.
We will use vellum to simulate butterfly wings and after that we will use particles simulation to emit particles from butterfly wings.
we will learn how to color our particles with image texture.
we will create smoke simulation and use the smoke simulation velocities to advect our particles.
we will learn how to import all our scene in to LOPs Solaris for lighting and shading and for rendering.
we will learn how to use the Karma XPU to render our magical fx.
And we will finish our course of by composting inside of after effects.
we will learn how we can import our rendered sequence and passes in the correct OCIO color space.
this course is for anyone who is looking to polish their houdini skills and want to add magical fx in their portfolio.
We got lot to cover so without further ado let's get to it
