Is it possible masking sprites by creating a shader.

[gouzhun]

Hi,I've searched all the forum topic, I know that sprite can not be masked and
UIPanel texture based clipping can not solved my problem.
My situation is :
1. UISprite icon represent weapon fragment which is a weapon icon with masked part.
2. Can't use UIPanel texture mask, because in bag, not just weapon fragment, but also
    Weapon, potion, cloth...
3. I have not only one mask type texture, so I can not put the mask data on the sprites
    texture's alpha channel.
4. Considered using UITexture, but worry about the performance.

So anybody has a solution for me,will really appreciate it. thanks~~

Use UITexture. There is no performance difference, you will just create 1 extra draw call, but that's it.
