Creek Shader Free
Install

Easy to use. Fast. Good realism. Has reflection, refraction, and fresnel. Variables added at the top of the shader so you can easily adjust the water color, creek speed, creek direction, ripple size, refraction amount, and fresnel intensity. I desaturated the skybox reflection in the water, and there's a subtle plane displacement in the vertex to give a rising and falling effect along the shoreline.

Notes:

Put the skybox texture in slot 0 on the material

Disable cast shadows on material

Enable z-sort on material

Make a box or plane and slap the material on it
