In this course, we'll go over how to create an explosion in Houdini, with no prior knowledge being required. We'll start by going over the basics of navigating and using Houdini, getting you comfortable with the software. Then we'll start creating the explosion and destruction effect step-by-step.  I not only explain how to make the effect, but why we use the nodes we do and how they work under the hood. Lastly, we'll quickly look at how to composite the render inside of Houdini.   Whether you're picking up Houdini for the first time or you're an intermediate user eager to expand your skill set, this course is tailored just for you.
