Im using SpriteAttacher but can't get the alpha right.
I can see in the video from @Mitch that the sprite has the standard import settings "Sprite (2D and UI)", if I use that I get white artifacts all over the transparent areas.
If i use advanced settings and untick "alpha is transperency" it gets much better but i will still get white borders around the sprite.
I have tried to add a Packing tag and use unitys sprite packer, but that doesn't show any changes.
What can I do? Should the image file have premultiplied alpha before i import to Unity? and if that is the case how can i do that?
Or is it something else that i need to do with my sprite?
