About this shader

I made a checkpoint shader for a game I am currently working on.

It was inspired by the red checkpoint shader in Grand Theft Auto San Andreas.

Steps To Setup:

Create A MeshInstance3D.
Assign it to a ShaderMaterial.
Adjust the Threshold and Error Correction as needed.
Colorize!

You Can Use It In Your Game and Edit It If Needed. Credit is appreciated but not required.

shader_type spatial;
render_mode cull_disabled;

varying vec3 vert;

uniform float threshold : hint_range(-1.0, 1.0, 0.1);
uniform float error_correction : hint_range(0.0, 1.0, 0.1);
uniform vec4 color : source_color;

void vertex() {
	vert = VERTEX;
}

void fragment() {
	ALBEDO = color.rgb;
	
	if (vert.y > threshold && vert.y < error_correction) {
		ALPHA = -vert.y * color.a;
	} else {
		ALPHA = 0.;
	}
}
