The opacity of camera shaders affects world objects

Help

Hello, I am a new user of Godot.

I created a shader on the camera, but I found that when I changed its opacity, the opacity of the MeshInstance3D object in the 3D scene also changed accordingly.

How can I make it not affect MeshInstance3D objects in the 3D scene?

my shader code:

shader_type spatial;
render_mode unshaded,cull_back;

uniform sampler2D SCREEN_TEXTURE : hint_screen_texture;



void vertex() {
	POSITION = vec4(VERTEX.xy, 1.0, 1.0);
}

void fragment() {

	vec4 original = textureLod(SCREEN_TEXTURE, SCREEN_UV, 0.0);

	ALBEDO = original.rgb;
	ALPHA=0.5;

}

What are you hoping to accomplish by setting alpha on the camera shader?

I am currently working on a tower defense game and I want to display the attack range of the turret. I have already implemented this feature, but it will affect the opacity of the health bars of other monsters, which is why I came here to seek help.

You can set opacity on objects directly by setting an alpha value in their self_modulate color. You could do that directly rather than via the camera…

Thank you for your help. I have resolved this issue by adjusting the rendering priority
