Soft alpha mask for scrollview

I was looking at https://bitbucket.org/ddreaper/unity-ui-extensions/wiki/Controls/SoftAlphaMask however, I can't seem to get it to work with a scrollview.

I have a standard ui scrollview with the scroll view -> viewport -> content on it. The content has a grid layout and a content size fitter. The scrollview "sits" inside a background image that has a bit of curve to it. The goal is to get the mask to also match this curve.

Using the standard mask, we get jagged lines since the alpha is either on or off. I can't seem to get the SoftAlphaMask to work though with this setup, so I was curious if anybody had another solution for this or knew a way to get this SoftAlphaMask from the ui Extensions project to work.

Thank you for your help.

 

Still could use some help on this. It looks like it might be possible with shaders, but I have not had much luck with the few I have found. I did see that Unity may have something in their new 2D experimental tools, but that is still in early beta and may not be the best option right now, nor is there currently an estimated release date.

There are some assets in the asset store that can do alpha blended UI masking, however not sure about how they work with text or scrollview:

Yeah, I had looked at those. The $10 one is actually also provided in the UI Extensions project, but I couldn't get it to work after trying several things. The $20 one does show some examples that is probably what the boss wants(the scrollview with alpha masking allowed), so it might be an option if we can't come up with another choice.

Thanks for the suggestions.

 

It's a bit too late, but yet another masking Asset has been published recently:

It's specialized to work with Unity UI. It behaves in the same way as Unity's standard mask but supports alpha. If you use standard Mask, you can just replace it with Soft Mask and everything should work. If you have disabled 'Show Mask Graphic' flag, you should also disable Graphic when using Soft Mask, as described in the documentation.

Well, that's enough advertising

What about https://bitbucket.org/ddreaper/unity-ui-extensions/wiki/Controls/SoftAlphaMask (thanks for the link, by the way!), I have read SoftMaskScript.cs. As I understand, you should set viewport's RectTransform as MaskArea property and the mask texture as AlphaMask property. The script should be added to every masked element, not to the mask. It would be a bit difficult to use if you have a complex UI hierarchy, especially if it's changed on-the-fly, but, for simple cases, that should work.

 

zxkne thank you very much.
