Alpha Channel in Unity Game Engine

Alpha Channel in Unity Game Engine

Unity uses straight alpha blending. Hence, you need to expand the color layers. The alpha channel in Unity will be read from the first alpha channel in the Photoshop file (read more at source).

***Rem)

For transparency, Unity can only support the alpha channel. Due to this, Unity provided an Action [AlphaUtility.zip as in the asset folder of this document, “2015 - SUMMARY-Unity3D-Part001.docx - Assets”] to be loaded into Photoshop. To understand this see Chapter 8 of http://www.digitaltutors.com/tutorial/603-Unity-Mobile-Game-Development-User-Interface-Design#overview.

Note: need to know masking to understand the last three lessons of http://www.digitaltutors.com/tutorial/603-Unity-Mobile-Game-Development-User-Interface-Design.
