Question

I have an animated Sprite3D that I want to be visible underneath occluding geometry. I want to use an xray shader to achieve this.

Currently I’m duplicating the original Sprite3D and applying a shader to the duplicate.

shader_type spatial;
render_mode unshaded, depth_draw_never;

uniform sampler2D albedo_texture : source_color;
uniform vec4 xray_color : source_color = vec4(0.0, 1.0, 1.0, 0.5);

void fragment() {
    vec4 tex = texture(albedo_texture, UV);

    if (tex.a < 0.1) {
        discard;
    }

    ALBEDO = xray_color.rgb;
    ALPHA = tex.a * xray_color.a;
}

But the effect isn’t working. Furthermore, this approach won’t automatically animate the xray sprite3d.

Is there a better way to do what I’m trying to do?
