What is it?

Fog Gradients is a Post-Process effect that allows you to layer different colors over distances and directions.

It uses Color Curves which can be edited in real time, giving you the freedom to create the perfect look for your environment, whether it be stylized or realistic. All of the many settings use tool-tips, customize the shader to suit your project's needs.


How do I use it?

It's easy, here's how to get started:

  1. Create a Color Curve
  2. Add Color Curve to the T_FogGradients Curve Atlas
  3. Create a Material Instance from M_FogMaster
  4. Inside the new Material Instance, set the Atlas Row to the corresponding row in the Curve Atlas
  5. Add a post-process volume (Make sure you're inside the volume)
  6. Add the Material Instance to the Post Process Materials Array
  7. Edit the Color Curve and Material Instance to get the desired looks that fit your scene.
