Using Portal Shaders in Unity
Portals are something that are used quite often in games in order to allow users to travel to different locations quickly. They also give us an opportunity to see how we can utilize time to adjust our shaders and utilize both the Twist and Voronoi nodes to great effect. In this recipe, we will create a portal shader using Shader Graph and the HDRP. We will begin by setting up a shader that applies a Twist effect to distort the portal’s appearance and use Voronoi noise to generate a dynamic, animated texture. Then, we will introduce time-based movement to make the portal feel alive. Finally, we will refine the effect by masking the edges, adding HDR color control, and ensuring proper transparency and blending for a polished look.
