Mask with NGUI

[Tatanan]

Hello.
Is there any way to make a mask with NGUI?
By "mask" I mean the mask Flash has, ie, an object which defines which part of another object is shown.

I already know that NGUI does have some kind of mask if you use a UISprite of type Filled. Then adjusting Fill Amount I can show more or less. But I wonder if I can make it better like I did it on Flash.
Example: cutting an image with a starred shape or so.

Thank you.

Yes. Panels let you specify a clipping mask texture.

As far as I know, panel mask are only rectangular.
Is there any way to use other shapes, like stars, circles, human-shapes or whatever?
I know that Unity UI has this kind of masks, but I don't know if it's compatible with NGUI.

Make the texture mask a circle, and there you go. Its a texture mask. Specify whatever you like. All textures are rectangles, doesn't mean that what you see has to be.

Oh, I just realised that you could specify a texture on the UIPanel to use as mask.
That's a great feature.

However I'm finding a problem. I'm attaching a screenshot. The mask is not working properly. The UISprite should be masked by a hand shaped mask, but there are also some extra lines on each direction.

That's your texture import settings. You have it set to Clamp, and your texture goes all the way to the edges of the texture.

Add some padding pixels.

I still don't know how to do it.
After your answer I have tried every texture type and I still can't make a "good" mask. The mask keeps adding 4 extra lines for each direction.

It's the same with other textures. Basically, the mask is not respecting the Size value and it's adding "extra lines".

I think you can hack it by giving the mask a 1px border of transparent color.

[ArenMook]

Exactly what Nicki said. The "white" of your texture should never go all the way to the edges of the clamped texture. Clamp = border pixels "repeats" forever.
