Basic Checkpoint

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:

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

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

Shader code

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.;
	}
}
