Using custom shader in pixi v4

[Exca]

I'm upgrading v3 project to v4 and I have some custom shaders done for few sprites. For some reason these dont get used in v4 no more. Should I use filters instead?

I'll create an example case if needed later this week.

API for shaders was changed.

http://pixijs.github.io/examples/index.html?s=basics&f=custom-filter.js&title=Custom%20Filter&v=dev works just fine.

Shader is:

precision mediump float;

varying vec2 vTextureCoord;
varying vec4 vColor;

uniform sampler2D uSampler;
uniform float customUniform;

void main(void)
{
   vec2 uvs = vTextureCoord.xy;

   vec4 fg = texture2D(uSampler, vTextureCoord);


   fg.r = uvs.y + sin(customUniform);

   //fg.r = clamp(fg.r,0.0,0.9);

   gl_FragColor = fg;

}
