Texture Generator & Effect for URP.
■ 1. Water Caustics Tex Generator [ URP / HDRP / Built-inRP ]
・Generates rich, realistic water caustics animated textures at runtime.
・If using only this generator, any render pipeline can be used. (However it is designed to be used in linear color space. If used in gamma color space, raise the value to a power of 1/2.2 at using.)
■ 2. Water Caustics Effect [ URP(3D) ]
・Supports only URP (Universal Render Pipeline).
・Apply caustics effects by specifying an area and a layer.
・Most opaque materials can get the effect without any modification.
・The vertex deformation shader and the alpha blending shader can get the effect by embedding custom functions into the shader. The Custom functions are supported for Shader Graph, HLSL scripting, and Amplify Shader Editor.
・Supports up to 9 Directional, Spot, and Point Lights. (Complies with URP specifications)
・Screen space shadows, added in URP 11.0 are supported.
・VR devices are supported.
