Underwater Camera effect

I modified this:

2D water effect

To work with 3d and have a customizable tint.

To use: put this shader on a plane, put the plane over the camera your using.

Shader code

shader_type spatial;
render_mode unshaded;

uniform vec4 tint : hint_color; // tint effect
uniform float wave_speed = 3.0; // wave loop speed
uniform float wave_freq = 10.0; // wave vertical freq
uniform float wave_width = 1; // wave width 

void fragment(){
	vec2 scale_UV = SCREEN_UV;
	vec2 wave_uv_offset;
	wave_uv_offset.x = cos((TIME*wave_speed)+UV.x+UV.y*wave_freq*2.0)*wave_width*0.01;
	ALBEDO = texture(SCREEN_TEXTURE, SCREEN_UV+wave_uv_offset).rgb*tint.rgb;
}
