Really basic question here that I could not find an answer to via search:
With the two camera setup, does transparency on the ngui sprite and camera affect the rendering of the main scene camera?
What I mean is, because the cameras are separate entities, is the transparency applied to the rendered frame (pixel level) or does it affect the rendering on a fragment level?
I'm trying to get my game to run on early devices, and I thought that I'd have to use square buttons but circular ones don't seem to affect rendering time in the editor at all.
