Shader Properties

How to use this asset.

This asset comes with a nice and clean material editor to edit the properties of the caustics. This editor will simply show up in the material section in the inspector if you have the caustics volume selected.

Texture

You can specify which caustics texture is used and at what scale it is displayed. You can also control the movement speed of the caustics.

Visuals

Here you can control the visuals of the caustics. There is a slider to control the intensity of the effect. The chromatic aberration slider controls how much the caustics appear to fall out into the RGB color channels. This is to mimic the light rays refracting through the water surface at different angles depending on the wavelength.

Light influence

The caustics may be influenced by the light in the scene. The luminance mask will mask out the caustics based on the scene luminance. This is to keep the caustics from showing up in shadowed areas.

Edge fading

The caustics will be shown within the caustics volume. To soften the edges of the caustics effect, you can fade them out towards the edges.
