I’ve been looking for a way to mask one sprite with another, and have found some interesting bits and pieces on the topic. However, none is excactly what I’m looking for.
What I need is to be able to mask a transparant sprite with another, including alpha gradients. This should theoretically be possible to accomplish, and I feel this kind of shader should come standard with Unity. Regardless, I’ve looked around and found these links that might help others:
Sprite Mask: [Released] Sprite Mask - masking system for Unity Sprite - Community Showcases - Unity Discussions
It’s a Sprite Mask asset for Unity. It looks great! But it doesn’t yet support alpha gradients… For any other masking purpose, though, it’s perfect.

Someone created an alpha gradient mask shader. Only problem is, it is limited to a pre-defined circular area, with a static centre and size.
My theory is that by combining the shaders of both could result in an alpha gradient sprite masking shader. Sadly, I have absolutely no experience with creating shaders, and every time I tried it ended up quite horribly.
So my question is… what alternatives are there, and what would you do when faced with this problem?
I hope the links help anyone out looking for sprite masking, by the way. ^^
