Problems with transparency

[ShabihK]

Hi! I'm using 2D toolkit for the animations that I make in Spine. When I want to reduce the opacity of and sprite it becomes darker that in the original animation. I think that maybe is fault of the shader and I must to use another (tk2d/BlendVertexColor). Do you have any suggestion?

This is the original animation:

And this is how it look in Unity:

tk2dBlendVertexColor simply outputs what it reads in. If you change the opacity of the sprite, more of the background will show through? Isn;t that whats happening?

The Background is the one that you can see in both images. The second image I took it from Unity and it's darker that the same frame in the animator tool and I wonder why.

Ok I solved adding a new material with another shader (Spine/Skeleton) in some textures and checking pre-multiply. Thank you
