Creating Particle Fog In Unity HDRP
Following yesterday’s post, I am creating some fog in my scene using Particle Systems, for atmospheric effect.
Today’s Objective: Create fog using the Particle System to add some atmospheric ambience to the sci-fi scene.
Particle System Fog:
To create a Particle System, right-click in the Hierarchy and select “Effects/Particle System”.
Next is to set up the Particle System to act like fog. Depending on the project, this can involve a lot of tweaking of the variables.
For this guide, I will just show how to set the shape, texture, and movement.
Since the smoke/fog texture is a spritesheet (a texture containing multiple slightly different images, combining to form an animation), I need to enable the Texture Sheet Animation module.
Note: The material shader I am using is from the Legacy section and is becoming outdated/replaced, but it works for now:
Increase emission rate, and decrease speed and lifetime. Set the Simulation Space to “World” if the Particle System will be moving (mine won’t, but I prefer setting it for good measure).
