Changing Shader or anything that can help improve the sprite's quality on Unity?

I tried LWF, it's working fine for me, but the texture of the animations looks surprisingly blur.
Here's an example of the sprite (displayed using 2dToolkit), and after it's displayed using LWF:

What Texture2D setting do you use? It seems the setting should be as the following.
Filter Mode: Point
Format: 16bit or Truecolor

[JakeL168]

This is the setting I use.

[JakeL168]

By the way, asides from the image setting you suggested, I've also tried every other combinations of texture settings, and non of them can give me the kind of effect I want.

[splhack]

could you share the texture file?

Here ya go:

Thanks. Would you try the latest code?

The previous implementation based on the following information. It seems it is not necessary for Ortho screen.

Compare to the original looks, the new one still looks very tessellated.
Plus, there's that artifacts for every time I play the animation (for all the textures involved).

[JakeL168]

Those artifacts never occur in the previous version though.

[splhack]

Could you try to set "Wrap Mode: CLAMP" on the texture inspector for the artifacts?

[JakeL168]

Oh yeah. Forget to set it to CLAMP. Yup, that seems to be the cause for the artifacts.

Hm, you are using 6x6 PNG file. Could you try to resize to 8x8 (add 2 transparent pixels for width and height)?

[JakeL168]

Tried 8x8, and it's definitely sharper, but not what I want~ :)

This may be related to the fact that the UV coordinates calculation appears to be wrong. If I create a 8x8 pixel texture and make it bigger in flash (say, 200x200), the LWF library samples up to half-pixel outside the 8x8 region in the texture sheet, so you will see how the 200x200 region in Unity blends to a different color...

[JakeL168]

But the thing is I didn't make it bigger in Flash, I retained its original size (8x8) in both the Flash file and in Unity. And the problem still occurs...

Perhaps Unity performs some interpolation and/or includes mipmaps if "Texture Type" is "Texture". Please try the following settings:

• Texture Type: Advanced
• Non Power of 2: None
• Generate Mip Map: Unchecked
• Wrap Mode: Clamp
• Filter Mode: Point (Bilinear is okay if the scale is one)

[JakeL168]

I've increased the size of the image from 8x8 to 32x32... and the result looks better now. It's really just the size problem I guess.
