Haxe

can you post the glsl code in backticks like this

\`\`\`glsl
// code here
\`\`\`
making it 
```glsl
gl_fragColor = vec4(1.0, 1.0, 1.0, 0.0);
```

```glsl
    #pragma header

    uniform float iTime;
    uniform vec2 iResolution;

    void main()
    {
        // uv (0 to 1)
        vec2 uv = openfl_TextureCoordv;
        
        // uv (-1 to 1, 0 - center)
        uv.x = 2. * uv.x - 1.;
        uv.y = 2. * uv.y - 1.;
        
        float barrel_power = 0.80; // increase for BIGGER EYE!
        float theta = atan(uv.y, uv.x);
        float radius = length(uv);
        radius = pow(radius, barrel_power);
        uv.x = radius * cos(theta);
        uv.y = radius * sin(theta);
        
        // uv (0 to 1)
        uv.x = 0.5 * (uv.x + 1.);
        uv.y = 0.5 * (uv.y + 1.);
    
        float chromo_x = 0.2;
        float chromo_y = 0.2;
        
        // output
        gl_FragColor = vec4(flixel_texture2D(bitmap, vec2(uv.x - chromo_x*0.016, uv.y - chromo_y*0.009)).r, flixel_texture2D(bitmap, vec2(uv.x + chromo_x*0.0125, uv.y - chromo_y*0.004)).g, flixel_texture2D(bitmap, vec2(uv.x - chromo_x*0.0045, uv.y + chromo_y*0.0085)).b, 1.0);;
    }
```

The thing is, whenever I apply it to camGame it works normally

But whenever I apply it to camHUD it makes everything under camHUD black

image

so, the problem is that the entire shader is using the same alpha

maybe you should get the alpha of the bitmap instead of making a solid 1.0 alpha?

i mean, the transparent color at the end of the day is just black with alpha set to 0

so, when you set it to 1, it becomes black

although why would everything be black when alpha is set to 0

you think it would just show the game cam

makes me think something else is the issue

if there's no shader on the hud cam does it looks normal?

the hud just shows over the game with no black covering

what happens if you do
```glsl
gl_FragColor = flixel_texture2D(bitmap, uv);
```

or maybe
```glsl
gl_FragColor = flixel_texture2D(bitmap, openfl_TextureCoordv);
```

why did backdrop have to change <a:dead:847199228962144287>
