URP Water

Documentation

Hand-coded for optimal performance and maximum customizability, URP Water is also simple to set up! No matter if your art direction is realistic or stylized, URP Water has plenty of options to match all of your needs.

- Features -

Dynamic Effects

Use any kind of renderer (particles, trail renderer, mesh, etc...) to dynamically affect the surface of the water. Using the provided shader, or your own, you can affect the normals, the foam and the displacement of the water surface.

Vertex Paint

You can manually add foam, mask displacement or change the opacity of the water, using vertex paint.

- Water Parameters -

Refraction

Use color pickers or the gradient editor to control the color of the water.

Select the depth range of the color mapping.

Control the amount of refraction distortion.

Specular

Specular highlights with color and smoothness control.

Normal Maps

Multiple modes with control over tiling, speed and intensity, including:

• Single Mode: One texture animated in 2 different directions
• Dual Mode: Two textures animated in 3 different directions
• Flow Map: Use a texture to define the flow direction of the water
• Facet: For a low poly-look
• Far Map: A different normal map is animated in 2 different directions when the water reaches a certain distance from the camera. You have control over what distance it happens.

Reflection

• Cubemap
• Reflection Probe
• Planar Reflection

Foam

• Edge foam
• Ripples
• White caps

Caustics

• 2D texture
• 3D texture
• React to shadows and light direction
• Angle mask

Displacement

• Gerstner Wave ( up to 4 waves )

Tessellation

• Edge length tessellation: the subdivisions adapt to the distance from the camera and the relative size of the edges.

Options

• Double-sided
• World space UV
• Orthographic camera support
• Vertex color effects
• Add foam
