Help with shaders

[SamuXDD]

So i'm trying to recreate Darnel bf mix and when i import the rain shader and code it to the game, but when i play the song the screen looks like dark grey.

here is the code that i wrote (i put this code in a stage with a script:

var rainShader:CustomShader = null;

rainShader = new CustomShader('rain');
rainShader.uTime = 0;
rainShader.uScale = FlxG.height / 200;
rainShader.uIntensity = 0.2;
rainShader.uScreenResolutionV = [FlxG.width ,FlxG.height];

var obj = new FlxSprite(0, 0).makeGraphic(FlxG.width ,FlxG.height, FlxColor.WHITE);
obj.shader = rainShader;

FlxG.camera.setFilters([new ShaderFilter(obj.shader)]);

Theres a port of it in the vslice-modpack pinned on the CodenameCrew organization page
