Stylized Water Shader
All the shaders in the package are one-sided. Meaning, if you move the camera beneath the water surface, it will appear invisible.
If this is an issue for you, duplicate your water object and flip it 180 degrees. It’s recommended to create a separate material for this object, so you can fine-tune it’s visual appearance.
Triggering post processing effects, such as screen waving and blurring, is possible through SC Post Effects, which includes an “Underwater” example profile.
