Some Shaders Don't Work

[msj121]

The following shader doesn't work:

Enter_The_Matrix.json

Uncaught TypeError: Cannot read property 'x' of undefined(…)

FWIW, I've gotten this exact error when using a custom shader (e.g. AFRAME.registerShader(...)) because of doing something like:

{
  uniforms: {
    foo: new THREE.Vector3()
  }
}

instead of:

{
  uniforms: {
    foo: {value: new THREE.Vector3()}
  }
}

So I would guess that a uniform is being set incorrectly somewhere in the shaderfrog->threejs conversion.

Oh wow! Thanks for the heads up! This will hopefully narrow down my search for the code issue.
