How to use GlowingQuad plugin?

I think I am getting somewhere. I added the three directional glows to the sphere using Child Actors

Now, I can see the glow for the XY plane:

A few issues:

  1. The other planes do not have a glow.

  2. I can only see the glow looking up from below the object.

  3. I set the color of the glow to blue, but it is still showing white. Here are the color settings:

  4. The glow is rectangular. I want it to follow the shape of the sphere.
