Q. How do I place OpenGLES Views to draw Live2D and other Views (like buttons, labels, and images)?
Do I need to draw all the buttons on OpenGLES?

 ※Common with iPhone and Android

A. If you layer the Live2D View and other button's View, there is no problem with the interactive applications however it degrades the performance.
We have tested of layering Views with all the applications (like HibikiDokei, etc.) as of Mar 2011, and we find no problem.

If you want to make it a better response when using it in the shooting games or action games, it seems to make it with better quality to use only one View (OpenGLES) and draw the buttons with OpenGLES.
