throttlekitty Posted November 13, 2010 Share Posted November 13, 2010 For the diffuse texture, alpha is used for opacity, and is needed if you intend any kind of transparency.For the Normal map, alpha is used for specularity (how shiny a given pixel is), and is generally needed always, even if set to all black (not shiny).
