How to Use

Clear Color Settings

To make transparent window, set Camera.ClearFlags to SolidColor, and the Camera.Background to (0,0,0,0). When set Camera.Background to (1,1,1,0), the result gets wrong.

Limitation

This is for Windows, not works on Mac or any others.

Transparency is ignored when use window mode in some laptop (especially when it use mobile type GPU). Need to use full-screen mode in such case.

In another way, use command-line option like a following and make the popup-window which has more over full-screen resolution.

-popupwindow -screen-width xxxx -screen-height xxxx

Tearing

Sometimes gets tearing and I can't find the cause. However, it is not serious.

Jaggy

There is a little jaggy even if use anti-aliasing, especially in low-dpi.

Anti-Aliasing

Some anti-aliasing shader gets wrong result.
