Is the "Unlit - Additive Colored" shader actually used within NGUI anywhere? I've started adding some visual effects to my UI using an additive texture atlas, but was surprised that the additive shader that comes with NGUI seems to ignore any tinting applied to widgets using that shader. My immediate need was to be able to adjust the alpha on the widget to fade in an out, but I could see wanting to tint things before adding. I've got another shader that meets my needs for the moment, but I was wondering what the deal was.
