Are you after a cutout effect?

If so connect the star_alpha outColor to the opacity instead of the transmission color or transmission. Make sure transmission is set to 0.0 as well other wise your base color map will have no effect.

You will need to set the file node to invert under effects as well.

I fix it. I turned down the IOR and it displayed just fine, although now I have a new problem. When using an img sequence it renders black? When I turn off img sequence it displays just fine. here is my setting for the alpha channel.
