Questions regarding Alpha

[Rahul26503326mxdg]

Hi,

I will use weld brush as an example Brush show Alpha weld in the alpha channel. 

1)Why does it show alpha like material sphere in the alpha channel. If I put any image as an alpha it show an image and not sphere.

2)Secondly where is this alpha I cannot find in substance painter

1. It depends how the icon was generated when the alpha was made. For example creating a material for an alpha in Designer can generate a spherical icon and include that in the sbsar file used for the alpha. The example below is two versions of the same custom font alpha. The first of which I did not generate an icon in Designer and the second of which I did.

2. The alpha shown, in your screenshot, is built into the brush preset (sppr) file and not stored separately.
