Join me as we explore the world of viscous fluids in Houdini. In this tutorial, we'll cover how to set up a flip simulation from scratch, and then we'll dive deeper into controlling the viscosity based on the age of the particle simulation. We'll also discuss collision techniques and provide helpful meshing tips after caching out the particle sim. Additionally, we'll touch on basic texturing and rendering setups for Redshift. By the end of this tutorial, you'll have a clear understanding of how to create controllable viscous simulations.
