Houdini realistic dynamic clouds – VFX GRACE

Hi there! It’s VFX Grace. This is an advanced tutorial on dynamic cloud simulation. Compared with the previous Realistic Dynamic Clouds tutorials, it employs some advanced techniques, which makes the controlling of the shape, the rolling dynamic, and the randomness of clouds more flexible and accurate, with a faster simulation based on Pyro Solver in Houdini18. Firstly, we will analyze the reference to catch the rules and features of the light dynamic cumulus from the aspects of dissipation, gravity, expansion, rolling, turbulence, continuous growing, etc. which greatly affect the realism of clouds. Then we will create and adjust the volume source and build the force fields to generate those features thus to achieve the desired dynamic. Starting from scratch, I will walk you through every step to get the final dynamic. For those who have some basic knowledge about Pyro Solver, this tutorial will definitely give you a more accurate and solid understanding of cloud simulation and dynamic control.
