Alpha for textures

[Hidden1One]

Do you need alpha channel for textures? what is it used for?

 

Normals? do they need the alpha channel? also what is it used for?

 

File-name_g.dds is that for glow?

anyone know?

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).
