Shader UV

How can I get this effect in Godot using a shader on a plane mesh?
I'm sure this is pretty simple but I cannot get my head around it.

From Blender:
Incoming:
Vector pointing towards the point the shading point is being viewed from.

You would use textureProj:

ALBEDO = textureProj(texture, VERTEX).rgb;

spacecloud
I tried it but now its like a static ui texture.
You mean like this?:

shader_type spatial;
uniform sampler2D noise;

void fragment() {
	ALBEDO = textureProj(noise, VERTEX).rgb;
}
