Issue upgrading threejs with shaders

问题

I am working on a 3d dataviz. I need to show a world with data on it and I using the chrome experiments (chromeexperiments.com/globe) as a guide.

The issue is that this visualizations are made with Threejs r40 and it is hard to find docs about it so I tried to upgrade to r71.

I solved the compatibility issues rendering the world but cant make it show the atmosphere, in fact, when I try to show the atmosphere nothing is shown (is like the atmosphere is rendered black and it hides the world).

I think that the problem is the shader but I am not really sure.

Does anybody have a clue?

This is the code I am using:

Thanks

Update:

if I remove the fragentShader, this is rendered as a red sphere but stills covers the world with a black background:

 var mesh = new THREE.Mesh(new THREE.SphereGeometry(100, 40, 30), 
        new THREE.ShaderMaterial({

          uniforms: uniforms,
          vertexShader: shader.vertexShader

        })
      );

The issue (as said by @WestLangley) was

mesh.flipSided = true; ==> mesh.material.side = THREE.BackSide;
