[Unity+tk2D] Weird artifacts showing up on sprites

SullyTheStrange

[SOLVED] TK2D has a "Premultiplied Alpha" setting in the sprite collections, I ticked the checkbox and boom, problem solved!

I don't know if this is a bug or something I'm doing wrong, but these faint boxes keep showing up behind certain sprites in my character's animation. They're very faint and you might have to zoom in to the example shoot below to see them, but they're behind the arrow and quiver, faint yellow boxes. Unfortunately they're still noticeable in-game so I can't ignore them. 🙁

I don't know what details will help so I'll regurgitate them all, I'm using Unity 4.3.3f1, using Spine 1.7.12, tk2d version 2.4.0, and the character's using Spine's Skeleton Lit shader. Any idea what's wrong?

If we need to zoom-in, maybe the image should be bigger. There's nothing to see here.

Things like this though are often a mismatch between the shader and the import and packing settings.

Note that SkeletonLit uses a premultiplied alpha algorithm for alpha blending. Make sure your settings aren't making colors bleed into the transparent areas whatever. I'm not familiar with TK2D myself so I'm not too sure where you can find these things.

Wow... well that was easy. TK2D has a "Premultiplied Alpha" setting in the sprite collections, I ticked the checkbox and boom, problem solved! Thanks for pointing me in the right direction.
