Vellum Sand Reveal – Houdini & Nuke VFX Course by Voxyde

Houdini

We will begin by creating a growth attribute that will serve as the main driver of our effects. This attribute will enable us to generate a growing VDB mesh and laser rays. We’ll also set up various custom attributes to aid in shading later on.

Additionally, we’ll generate smoke where the laser interacts with the geometry and create a simple fog volume to add ambiance to the scene. Apart from the provided helmet geometry, we’ll create everything from scratch directly inside Houdini.

Rendering

For rendering, we’ll use Redshift. After setting up all the materials, we’ll cover the best ways to configure various render passes for compositing.

Nuke Compositing

Finally, we’ll bring everything together in Nuke, starting by recreating the beauty pass. By separating all our AOVs, we will have complete control over all aspects of the render, such as reflection, specular, and GI.

We’ll combine custom passes and attributes to create new layers, adding more detail to the scene.
