➡ Manual PDF

This asset contains two modules:

a Texture Generator and an Effect.

■ 1. Water Caustics Tex Generator [ URP / HDRP / Built-inRP ]

• Generates rich, realistic animated caustic textures at runtime using a Compute Shader to simulate waves and light refraction.

• Supports both realistic and cartoon-like styles.

• This module works with all rendering pipelines.

• All parameters can be controlled via script.

• [Features] 4 Wave Layers, 3 Drawing Styles, Chromatic Aberration, Blur, Directional Blur, RGB Color Shift, Gamma, Brightness Adjustment, etc.

■ 2. Water Caustics Effect [ URP(3D) only ]

• Applies caustic effects using the camera's depth and normal textures.

• VR supported.

• Supports Forward, Forward+, Deferred, and Deferred+.

• All parameters can be controlled via script.

• Can also be applied individually by embedding a Custom Function in shaders. This method works for materials not rendered in the depth texture, such as transparent materials. (Supports Shader Graph, HLSL, and Amplify Shader Editor.)

• [Features] Range control with Rectangle/Image/Stencil masks, attenuation by depth and distance, random texture tiling, texture rotation, RGB Color Shift, transparency effect, render timing adjustment, etc.

[ Unity 2020.3 LTS or higher supported ]
